EdexcelHigherOld spec4 marksTransformations of Shapes

Grid with x from -8 to 8 and y from -8 to 8; shape A with vertices (1, 2), (1, 5), (3, 5) and (6, 2); shape B with vertices (1, -4), (1, -7), (3, -7) and (6, -4)

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

(b) On the grid, rotate shape A 90° anticlockwise about (0, 0)
Label the new shape C. (2)
