Exemplar responses for Q2d
| Response | Mark |
|---|---|
| Not all parallelograms have 2 order of rotational symmetry | 1 |
| Because some parallelograms have 4 lines of symmetry | 1 |
| Some parallelograms have more than order 2 rotation | 1 |
| Because there can be more than two lines of symmetry | 1 |
| A square has more than 2 lines of symmetry, it has 4 | 1 |
| Not all parallelograms have 2 lines of symmetry | 1 |
| They do not have 2 lines of symmetry as only two of the sides are equal in length (statement in bold would score 1) | 0 |
| Because a square is a parallelogram, has 4 lines of symmetry and rotation symmetry of 1 (statement in bold would score 1) | 0 |
| Parrallelograms have no line of symmetry and 0 rotation symmetry (statement in bold would score 1) | 0 |
| Parallelograms have more than 2 lines of symmetry | 0 |
| The rotational symmetry would not be 2 as you can only turn it once and make it the same | 0 |
