Islamic Geometric Ornaments in Istanbul
►SKETCH 2 CONSTRUCTIONS OF REGULAR POLYGONS Regular polygons are the base elements for constructing the majority of Islamic geometric ornaments. Of course, in Islamic art there are geometric ornaments that may have different genesis, but those that can be created from regular polygons are the most frequently seen in Istanbul. We can also notice that many of the Islamic geometric ornaments can be recreated using rectangular grids like the ornament in our first example. Sometimes methods using rectangular grids are much simpler than those based or regular polygons. Therefore, we should not omit these methods. However, because methods for constructing geometric ornaments based on regular polygons are the most popular, we will spend relatively more time explor- ing them. Before, we start developing some concrete constructions it would be worthwhile to look into a few issues of a general nature. As we have no- ticed while developing construction of the ornament from the floor in the Sultan Ahmed Mosque, these constructions are not always simple, and in order to create them we need some knowledge of elementary geometry. On the other hand, computer programs for geometry or for computer graphics can give us a number of simpler ways to develop geometric fig- ures. Some of them may not require any knowledge of geometry. For ex- ample, we can create a regular polygon with any number of sides by rotat- ing a point around another point by using rotations 360/n degrees. This is a very simple task if we use a computer program and the only knowledge of geometry we need here is that the full angle is 360 degrees. -

Framing Cyclic Revolutionary Emergence of Opposing Symbols of Identity Eppur Si Muove: Biomimetic Embedding of N-Tuple Helices in Spherical Polyhedra - /
Alternative view of segmented documents via Kairos 23 October 2017 | Draft Framing Cyclic Revolutionary Emergence of Opposing Symbols of Identity Eppur si muove: Biomimetic embedding of N-tuple helices in spherical polyhedra - / - Introduction Symbolic stars vs Strategic pillars; Polyhedra vs Helices; Logic vs Comprehension? Dynamic bonding patterns in n-tuple helices engendering n-fold rotating symbols Embedding the triple helix in a spherical octahedron Embedding the quadruple helix in a spherical cube Embedding the quintuple helix in a spherical dodecahedron and a Pentagramma Mirificum Embedding six-fold, eight-fold and ten-fold helices in appropriately encircled polyhedra Embedding twelve-fold, eleven-fold, nine-fold and seven-fold helices in appropriately encircled polyhedra Neglected recognition of logical patterns -- especially of opposition Dynamic relationship between polyhedra engendered by circles -- variously implying forms of unity Symbol rotation as dynamic essential to engaging with value-inversion References Introduction The contrast to the geocentric model of the solar system was framed by the Italian mathematician, physicist and philosopher Galileo Galilei (1564-1642). His much-cited phrase, " And yet it moves" (E pur si muove or Eppur si muove) was allegedly pronounced in 1633 when he was forced to recant his claims that the Earth moves around the immovable Sun rather than the converse -- known as the Galileo affair. Such a shift in perspective might usefully inspire the recognition that the stasis attributed so widely to logos and other much-valued cultural and heraldic symbols obscures the manner in which they imply a fundamental cognitive dynamic. Cultural symbols fundamental to the identity of a group might then be understood as variously moving and transforming in ways which currently elude comprehension. -
Applying the Polygon Angle
POLYGONS 8.1.1 – 8.1.5 After studying triangles and quadrilaterals, students now extend their study to all polygons. A polygon is a closed, two-dimensional figure made of three or more non- intersecting straight line segments connected end-to-end. Using the fact that the sum of the measures of the angles in a triangle is 180°, students learn a method to determine the sum of the measures of the interior angles of any polygon. Next they explore the sum of the measures of the exterior angles of a polygon. Finally they use the information about the angles of polygons along with their Triangle Toolkits to find the areas of regular polygons. See the Math Notes boxes in Lessons 8.1.1, 8.1.5, and 8.3.1. Example 1 4x + 7 3x + 1 x + 1 The figure at right is a hexagon. What is the sum of the measures of the interior angles of a hexagon? Explain how you know. Then write an equation and solve for x. 2x 3x – 5 5x – 4 One way to find the sum of the interior angles of the 9 hexagon is to divide the figure into triangles. There are 11 several different ways to do this, but keep in mind that we 8 are trying to add the interior angles at the vertices. One 6 12 way to divide the hexagon into triangles is to draw in all of 10 the diagonals from a single vertex, as shown at right. 7 Doing this forms four triangles, each with angle measures 5 4 3 1 summing to 180°. -
Polygon Review and Puzzlers in the Above, Those Are Names to the Polygons: Fill in the Blank Parts. Names: Number of Sides
Polygon review and puzzlers ÆReview to the classification of polygons: Is it a Polygon? Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up). Polygon Not a Polygon Not a Polygon (straight sides) (has a curve) (open, not closed) Regular polygons have equal length sides and equal interior angles. Polygons are named according to their number of sides. Name of Degree of Degree of triangle total angles regular angles Triangle 180 60 In the above, those are names to the polygons: Quadrilateral 360 90 fill in the blank parts. Pentagon Hexagon Heptagon 900 129 Names: number of sides: Octagon Nonagon hendecagon, 11 dodecagon, _____________ Decagon 1440 144 tetradecagon, 13 hexadecagon, 15 Do you see a pattern in the calculation of the heptadecagon, _____________ total degree of angles of the polygon? octadecagon, _____________ --- (n -2) x 180° enneadecagon, _____________ icosagon 20 pentadecagon, _____________ These summation of angles rules, also apply to the irregular polygons, try it out yourself !!! A point where two or more straight lines meet. Corner. Example: a corner of a polygon (2D) or of a polyhedron (3D) as shown. The plural of vertex is "vertices” Test them out yourself, by drawing diagonals on the polygons. Here are some fun polygon riddles; could you come up with the answer? Geometry polygon riddles I: My first is in shape and also in space; My second is in line and also in place; My third is in point and also in line; My fourth in operation but not in sign; My fifth is in angle but not in degree; My sixth is in glide but not symmetry; Geometry polygon riddles II: I am a polygon all my angles have the same measure all my five sides have the same measure, what general shape am I? Geometry polygon riddles III: I am a polygon. -

The Church of England, which buried him, or the Glastonbury pagans who cele - brated his birthdays and wedding? The Forteans on both sides of the Atlantic, knowing who was his favourite philosopher after Plato? The pilgrims whom he fluently guided around Holy Russia? The Old Eton - ians and the caste to which he was born? The old rock stars who knew him as pictured in David Bailey’s book of Sixties portraits, Goodbye Baby and Amen? Ufologists, honoured by his very first book? Ley hunters and earth mysteries folk? Students of crop-circles and other anomalous pheno mena? Sacred geometers and ancient metrologists? Grown-up children who see through every emperor’s new clothes? By common standards John’s life was mildly eccentric, his notions very peculiar. For one thing, he was nocturnal. The flat at the top of his Notting Hill house seemed a philosopher’s eyrie as one watched the sun setting over London’s roofscape. Then as the candles were lit, the curtains drawn, it was more of a hobbit smial, or Badger’s burrow. -
Formulas Involving Polygons - Lesson 7-3

By drawing as many diagonals as we could from one diagonal, you should be able to see a pattern...we can make n-2 triangles in a n-sided polygon. Given this information and the fact that the sum of the interior angles of a polygon is 180°, we can come up with a theorem that helps us to figure out the sum of the measures of the interior angles of any n-sided polygon! Baroody Page 3 of 6 Honors Geometry Notes Next, let’s look at exterior angles in a polygon. First, consider the exterior angles of a pentagon as shown below: Note that the sum of the exterior angles is 360°. -
Polygrams and Polygons
Poligrams and Polygons THE TRIANGLE The Triangle is the only Lineal Figure into which all surfaces can be reduced, for every Polygon can be divided into Triangles by drawing lines from its angles to its centre. Thus the Triangle is the first and simplest of all Lineal Figures. We refer to the Triad operating in all things, to the 3 Supernal Sephiroth, and to Binah the 3rd Sephirah. Among the Planets it is especially referred to Saturn; and among the Elements to Fire. As the colour of Saturn is black and the Triangle that of Fire, the Black Triangle will represent Saturn, and the Red Fire. The 3 Angles also symbolize the 3 Alchemical Principles of Nature, Mercury, Sulphur, and Salt. As there are 3600 in every great circle, the number of degrees cut off between its angles when inscribed within a Circle will be 120°, the number forming the astrological Trine inscribing the Trine within a circle, that is, reflected from every second point. THE SQUARE The Square is an important lineal figure which naturally represents stability and equilibrium. It includes the idea of surface and superficial measurement. It refers to the Quaternary in all things and to the Tetrad of the Letter of the Holy Name Tetragrammaton operating through the four Elements of Fire, Water, Air, and Earth. It is allotted to Chesed, the 4th Sephirah, and among the Planets it is referred to Jupiter. As representing the 4 Elements it represents their ultimation with the material form. The 4 angles also include the ideas of the 2 extremities of the Horizon, and the 2 extremities of the Median, which latter are usually called the Zenith and the Nadir: also the 4 Cardinal Points. -

Moon Violet Enneagram Camphor Element Color Odor Fire Red Cinnamon Water Blue Cedar Air Yellow Sandalwood Earth Black Myrrh DIAGRAM 66 The Triangle The first linear shape, associated with the sephirah Binah and the planet Saturn. Medieval sorcerers used triangles to bind spirits because they believed the limiting force of the triangle would confine the spirit. The triangle may be used in any effort to restrict, structure or limit anything. The number three also indicates cycles and therefore time, also a limiting factor appropriate to Saturn. The Square The square is related to Chesed, whose number is four. A square implies the form of a castle or walled structure, society, prestige, rulership and other Jupiterean qualities. The square also symbolizes structure beyond walls, it represents a completion or perfection; a "square deal" and three "square meals" a day illustrate the archetypal idea verbally. Also the four elements working in balanced harmony. The Pentagram The pentagram is the Force of Mars, and the sephira Geburah. -

An English Song Line
An English Songline by JAG Maw October 1986, a steamy college cellar somewhere under Cambridge. Lighting way low, amps buzzing gently, student chatter picked up by the stage mics, PA system on the edge of feedback. I was sitting on a monitor with a post-gig pint and talking rubbish to anyone prepared to listen. A bloke sidled up to Join the chat. I was immediately impressed by his leather Jacket. Not some chained-up bogus biker Job: this one had lapels. Like David Sylvian’s on the Quiet Life cover, only black. Very cool. But hang on a minute. Is that? I squinted. Out of each sleeve poked the tiny, whiskered and unmistakable face of a rat. Each would tip-toe occasionally down a thumb to sniff the air, have a rather pleased sip of beer and then disappear back into its sleeve. A Londoner taught to identify these creatures with the Plague, I raised an eyebrow. The rats were introduced to me as Sly and Robbie, and leather Jacket bloke introduced himself as a guitarist. “I think you need a new one,” he said. A new guitarist? It was hard to disagree. As the singer, I had decided that my Job was to write inscrutable lyrics and then deliver them with unshakable conviction. Musically, however, I relied on the honourable excuses of punk rock. My guitar tended to run out of ideas after five chords (that’s including the minors), and then turn into a stage prop. I went off to confer with the other band members, and told them about leather Jacket guitarist and Sly and Robbie. -

The Enneagram in the Writings of Gurdjieff presents a unified solution to a number of mysteries connected with his writings The Enneagram in the Writings of Gurdjieff with the emblem of his teaching, a geometric figure known as the enneagram. Gurdjieff called the enneagram the philosopher's stone of the alchemists and a source of great power, yet he never explained it satisfactorily to his pupils. This book shows that Gurdjieff transmitted through his writings an understanding of the symbol that he chose not to divulge in his talks. It also shows that the emblem of his teaching can be seen in the large-scale structure of his writings if one knows how to look The Enneagram in the Writings of Gurdjieff the surface.
