Foundation November 2023 Paper 2 Q19
19 Describe fully the single transformation that maps shape A to shape B. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Alternative method 1 | ||
| Rotation | B1 | |
| 180° or half turn | B1 | ignore clockwise or anticlockwise |
| Origin or (0, 0) or \(O\) | B1 | |
| Alternative method 2 | ||
| Enlargement | B1 | |
| (Scale factor) \(-1\) | B1 | |
| Origin or (0, 0) or \(O\) | B1 | |
Additional guidance
| Accept eg rotate for rotation and condone rotational symmetry | |
| Do not accept turn for first B1 | |
| Accept 180 for 180° | |
| Accept 0, 0 for origin | |
| Do not accept centre of grid for origin | |
| Reflection on (0, 0) | B0B0B1 |
| Choice of transformations eg rotation (and) \(\begin{pmatrix} 4 \\ 4 \end{pmatrix}\) or rotation (and) flip | 1st B0 |
| Combined transformation | max B0B1B1 |
