St+Philip%27s+CE+Primary+School Page 5 of 14 Adam has this rectangular piece of card. It is marked with grid lines. 8
Adam makes two straight cuts along the grid lines.
The two cuts divide the rectangle into 3 shapes:
• 2 squares of different size, and
• 1 rectangle.
Using the grid lines, draw two lines that show where Adam could have made his cuts.
Use a ruler. 1 mark

St+Philip%27s+CE+Primary+School Page 13 of 14 An explanation showing an understanding: 11 • that this specific triangle has angles 70, 70 and 40
OR
• of the properties of an equilateral triangle − all angles are equal (60°)
and therefore that this triangle cannot be equilateral, e.g.
• The angles aren’t 60° • There is not a 60° angle • It has two different angles (70° and 40°) so it can’t be equilateral • The angles aren’t the same • An equilateral triangle has 60° + 60° + 60° • All the angles are the same in an equilateral triangle • It’s an isosceles triangle.
(In the context of this question, the term isosceles triangle is treated as not including equilateral triangles as a special type, as the national curriculum does not specify this at key stage 2.) Do not accept vague or incomplete explanations, e.g. • The other angle is 70° • They aren’t (all) the same. (No reference to angles) • An equilateral triangle has equal angles. (Does not say all.) Do not accept explanations which include incorrect mathematics or incorrect information that is relevant to the explanation, e.g. • 40 + 70 = 110 + 70 = 180 [1]
Award TWO marks for a completed triangle that has all of the following three points: 12 • an angle in the range 33° to 37° inclusive for the angle marked 35° • an angle in the range 88° to 92° inclusive for the right angle • the triangle has been drawn on an 8cm line (either on the given line or a line drawn), provided they have constructed both angles within the tolerance of the line 7.9 cm to 8.1 cm.
If the answer is incorrect, award ONE mark for a completed triangle and TWO of the three points correct. Accept drawings where any side has been extended past a vertex. When considering whether the triangle is completed, do not accept: • a quadrilateral or another shape drawn OR • a curved line that is used to complete the shape OR • sides not meeting to form a vertex. Up to 2m [2]
