Foundation June 2019 Paper 1 Q11
11 Here is a triangle on a square dotty grid.
(a) On the grid below, show how you can make a parallelogram with two of these triangles. [1 mark]
(b) On the grid below, show how you can make a trapezium with three of these triangles. [1 mark]
(c) On the grid below, show how you can make a rhombus with four of these triangles. [1 mark]
| Answer | Mark | Comments |
|---|---|---|
| Correct shape drawn in any orientation | B1 |
Additional guidance
eg | B1 |
| Mark intention with regard to vertices on dots and use of straight lines | |
| Condone wrong size triangles drawn, as long as they are right-angled, scalene and congruent | |
| Internal lines must be drawn to show position of triangles | |
| Allow students to extend grid with dots but shapes not on (extended) grid cannot score |
