Higher November 2023 Paper 4 Q13
13 Triangle T and triangle A are drawn on the coordinate grid.
(a) Describe fully the single transformation that maps triangle T onto triangle A. [3]
(b) Describe fully the single transformation that is equivalent to:
- a rotation of 90° clockwise about centre (0, 0), followed by
- a reflection in the y-axis.
You may use the grid above to help you. [3]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Enlargement [centre] (−1, −1) [sf] −2 | 3 | B1 for each | If more than one transformation award 0 |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Reflection | 2 | M1 for correct final image of their starting object | If more than one transformation award only M1 if applicable |
| \(y = -x\) | 1 | If using triangle T the image will have vertices at (−1, −1) (−1, −4) and (−2, −1) | |
