Each segment that forms a polygon is a side of the polygon. The common endpoint of two sides is a vertex of the polygon. A segment that connects any two nonconsecutive vertices is a diagonal. You can name a polygon by the number of its sides. The table shows the names of some common polygons. All the sides are congruent in an equilateral polygon. All the angles are congruent in an equiangular polygon. A regular polygon is one that is both equilateral and equiangular. If a polygon is not regular, it is called irregular. A polygon is concave if any part of a diagonal contains points in the exterior of the polygon. If no diagonal contains points in the exterior, then the polygon is convex.

  • CH3 Test: Polygons, Quadrilaterals and Circles
    MTH 351 Review Sheet 1 CH3 Test: Polygons, Quadrilaterals and Circles Polygons Definition – How do we define polygons? Vocabulary : Side, Vertex, Diagonal, Interior angle, Exterior angle; Regular polygon Convexity and concavity of figures and polygons – what is a convex/non-convex figure? Make sure you know to classify figures such as those on the right. Classification of polygons. How do we classify/name polygons? What is a regular polygon? Interior angles sum . Find the sum of interior angles of (any) given polygon (see pictures). You also should be able to derive (justify) the formula for interior angle sum of a n-sided polygon. (Hint: recall #2 and 3 on pg.56) Find an interior angle of a regular pentagon. (Hint: First find the sum of all interior angles in a pentagon and then calculate the measure of one angle.) True or false? If it is false, draw a counterexample. • A regular polygon is always equilateral. • An equiangular polygon is also equilateral. • Pentagon that has all sides congruent is a regular pentagon. Etc. Quadrilaterals Definition – How do we define quadrilaterals? What do you know about the definitions of a trapezoid and kite? Each has two significantly different definitions - explain the difference (“modern” and “traditional”). Classification of quadrilaterals. Use Venn Diagram to classify quadrilaterals (use the traditional definitions of trapezoid and kite). Draw a typical representative in each region of your Venn Diagram. How would the diagram change if you were to use trapezoid’s “modern” definition? Answer the following questions or decide if the statements are true or false and justify your answer.
