Higher November 2021 Paper 6 Q4
4 Triangle A and triangle B are drawn on the coordinate grid.

(a) Reflect triangle A in the line \(x = 0\). [2]
(b) Describe fully the single transformation that maps triangle A onto triangle B. [3]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Triangle at (−8, 6), (−8, 2), (0, 6) | 2 | B1 for reflection in \(x = k\) or in \(y = 0\) | Mark intention, condoning freehand |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Enlargement [sf] \(\frac{1}{4}\) or 0.25 [centre] (0, −6) | 3 | B1 for each element | Marks spoilt if extra transformations Condone omission of brackets Accept centre as a vector |
