Foundation November 2021 Paper 1 Q11
11 Complete the diagram so that it has
rotational symmetry of order 4
centre of rotation at point A. [2 marks]

| Answer | Mark | Comments |
|---|---|---|
| Fully correct diagram with rotational symmetry of order 4 and centre of rotation at point A | B2 | B1 a correct rotation of the given triangle through 90° or 180° or 270°, centre of rotation at point A |
Additional guidance
![]() | B2 |
| Mark intention | |
| Where there are more than 3 extra triangles drawn on the diagram, award B1 if at least one is correct | |
| Students may amend original diagram (but still include the given triangle) and then use their new shape to give a diagram with rotational symmetry order 4 and centre of rotation at point A for B2 For B1, their new shape must be seen with a correct rotation through 90° or 180° or 270°, centre of rotation at point A |
