(a) Describe fully the single transformation that maps triangle A onto triangle B. (3)
(b) On the grid, translate triangle A by the vector \(\begin{pmatrix} 5 \\ -4 \end{pmatrix}\)
Label the new shape C. (1)
Label the new shape C. (1)

(c) On the grid, rotate triangle D 90° anticlockwise with centre (3, 1) (2)
| Scheme | Marks |
|---|---|
| Enlargement | B1 |
| Scale factor 2 | B1 |
| Centre (1, 0) | B1 |
| (3) |
Notes
B1: For Enlargement
B1: For (Scale factor =) 2
B1: For (Centre) (1, 0)
NB if more than one transformation mentioned then no marks.
| Scheme | Marks |
|---|---|
| Correct triangle at (10, −2), (7, −2), (7,−1) | B1 |
| (1) |
Notes
B1: Correct triangle in correct place
| Scheme | Marks |
|---|---|
| M1 | |
| Correct triangle at (1, 0),(2, 0),(2, 3) | A1 |
| (2) |
Notes
M1: Triangle congruent to D and with correct orientation
A1: ScB1 for triangle with vertices at (4, 2), (5, 2) and (4, −1)
