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

(a) On the grid, rotate triangle A 90° anticlockwise about centre \(O\) (2)

Grid with x from -2 to 10 and y from -2 to 10 showing triangle B with vertices (1, 2), (1, 3) and (3, 2) and triangle C with vertices (3, 6), (3, 9) and (9, 6)

(b) Describe fully the single transformation that maps triangle B onto triangle C (2)

Mark scheme (a)

Scheme	Marks
Correct rotation	B2
	(2)

Notes

B2: for a fully correct rotation at (1, 2) (3, 2) (3, 5)

(B1 for the triangle in correct orientation and size or
rotated 90° clockwise about the origin (–1, –2) (–3, –2) (–3, –5))

Mark scheme (b)

Scheme	Marks
Enlargement, scale factor 3 and (0,0)	B2

Notes

B2: for enlargement, scale factor 3 and (0,0)

(B1 for 2 correct from

for enlargement, enlarge, etc so long as no mention of rotation, reflection or translation, flip, move etc.
