Grid with x and y from −6 to 6 showing triangle A with vertices (3, 1), (3, 2) and (5, 1)

(a) On the grid, rotate triangle A 180° about (1, −1)
Label the new triangle B (2)

(b) On the grid, translate triangle A by the vector \(\begin{pmatrix} -7 \\ 3 \end{pmatrix}\)
Label the new triangle C (1)

Mark scheme (a)

Notes

B2: for a correct triangle with correct orientation and position

If not B2 then award B1 for a correct triangle drawn with correct orientation in wrong position or triangle drawn with 2 out of 3 correct vertices
