5
(a) Describe fully the single transformation that maps triangle A onto triangle B. (3)
(b) On the grid, translate triangle A by the vector \(\begin{pmatrix} 5 \\ -2 \end{pmatrix}\) (1)
| Scheme | Marks |
|---|---|
| Enlargement | B1 |
| (scale factor) 2 | B1 |
| (centre) (1, 3) | B1 |
| (3) |
Notes
B1: condone missing brackets around (1, 3); do not accept \(\begin{pmatrix} 1 \\ 3 \end{pmatrix}\)
These marks are independent but award no marks if the answer is not a single transformation
