4MA0 Foundation June 2011 Paper 1 Q19
19
(a) Describe fully the single transformation which maps triangle P onto triangle Q. (3)
(b) Reflect triangle Q in the line \(y = x\).
Label the new triangle R. (2)
Label the new triangle R. (2)
| Scheme | Marks |
|---|---|
| Rotation | B1 |
| 90° clockwise | B1 |
| (0, 0) | B1 |
| (3) |
Notes
B1: Also accept ‘rotate’, ‘rotated’ etc
B1: Also accept quarter turn clockwise, −90° or 270°
B1: Also accept origin, O
These marks are independent but award no marks if the answer is not a single transformation
| Scheme | Marks |
|---|---|
| vertices (4, 4), (4, 2), (5, 2) R correct | B2 |
| (2) | |
| (Total 5 marks) |
Notes
B2: Condone omission of label
B1 for 2 correct vertices
