Coordinate grid from −8 to 8 on both axes showing three L-shapes: A with vertices including (−5, 3), (−3, 3), (−3, 6), (−4, 6), (−4, 4), (−5, 4); B with vertices including (5, 3), (7, 3), (7, 4), (6, 4), (6, 6), (5, 6); C with vertices including (3, −5), (6, −5), (6, −6), (4, −6), (4, −7), (3, −7)

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

(b) Describe fully the single transformation that maps shape B onto shape C. (3)

Notes

B1: for rotation with no mention of translate, reflect, enlarge, move

B1: for 90° clockwise/270° anticlockwise/−90° with no mention of a vector, line of symmetry or scale factor

B1: for (centre =) (0,0), accept origin or \(O\) with no mention of a vector, line of symmetry or scale factor
Do not accept \(\begin{pmatrix} 0 \\ 0 \end{pmatrix}\) for centre
