13 Triangle A and triangle B are shown on the coordinate grid.
Triangle A is mapped onto triangle B using a combination of two transformations:
- a transformation T, followed by
- a translation of \(\begin{pmatrix} 8 \\ -5 \end{pmatrix}\).
Describe fully transformation T. [4]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Rotation | 2 | B1 for triangle or vertices at (−5, 1), (−1, 1) and (−1, −2) | Must be rotate or rotation, not turn etc |
| 90° [anticlockwise] or 270° clockwise | 1 | ||
| (−1, 3) | 1 | Condone −1, 3 Condone an answer [for full or part marks] that repeats the given transformation ie rotation, 90° [anticlockwise], (−1, 3) followed by translation \(\begin{pmatrix} 8 \\ -5 \end{pmatrix}\) In other cases: If more than one transformation stated then max award is the B1 for the triangle or vertices if drawn on the grid | |
