Grid with x and y from -8 to 8; shape A in the first quadrant and shape B its mirror image to the left

(a) Describe fully the single transformation that maps shape A onto shape B. (2)

(b) On the grid, rotate shape A 90° clockwise about the origin \(O\).
Label the new shape C. (2)

Scheme	Marks
Reflection	B1
(in line) \(x = -2\)	B1
	(2)

Mark scheme (b)

Scheme	Marks
Shape in correct position	B2
	(2)
	(4 marks)

Notes

B2: vertices at (1, –1) (7, –1) (7, –4) (4, –4) (4, –2) (1, –2)
Condone omission of inner square and/or omission of shading and/or omission of the label ‘C’
If not B2 then B1 for correct orientation but wrong position
or B1 for rotation 90° anticlockwise about (0,0)
