(a) Describe fully the single transformation which maps triangle P onto triangle Q. (2)
(b) Describe fully the single transformation which maps triangle P onto triangle R. (3)
| Scheme | Marks |
|---|---|
| translation 3 squares to the right and 1 square down | B2 |
| (2) |
Notes
B2: B1 for translation
Accept translate, translated etc
B1 for 3 right and 1 down (accept ‘across’ instead of ‘to the right’) or \(\begin{pmatrix} 3 \\ -1 \end{pmatrix}\) but not (3, −1)
These marks are independent but award no marks if answer is not a single transformation
| Scheme | Marks |
|---|---|
| rotation of 90° clockwise about (2, −1) | B3 |
| (3) | |
| (5 marks) |
Notes
B3: B1 for rotation
Accept rotate, rotated etc
B1 for 90° clockwise or −90° or 270°
B1 for (2, −1)
These marks are independent but award no marks if answer is not a single transformation
