18. The grid below shows triangle A and triangle B.

(a) Describe fully the single transformation that maps triangle A onto triangle B. [2]

(b) Translate triangle A using the vector \(\begin{pmatrix}-3\\2\end{pmatrix}\), label it C. [2]

Mark scheme (a)

Scheme	Marks	Comments
All three elements correct: rotation 90° clockwise or 270° anticlockwise about the origin or (0,0).	B2	B1 for one of the following: Rotation 90° Rotation 270° Rotation about the origin or (0,0) 90° clockwise about the origin or (0,0) 270° anticlockwise about the origin or (0,0) Note: Allow the origin to be written as 0,0 without brackets but not as 0.

Scheme	Marks	Comments
Correct translation i.e. 3 squares to the left and 2 up	B2	B1 for a correct horizontal or vertical translation Note: mark a correct translation of triangle B as a mis-read.
