(a) Shade the least number of squares so that the grid has rotational symmetry of order 2.
The squares you shade must be in the upper two quadrants. [2]
8 by 8 square grid divided into four quadrants by thick lines; in the lower quadrants a 2 by 2 block is shaded at the far left of the top two rows, and a vertical bar of 3 squares is shaded in the second column of the lower right quadrant
(b) Describe fully the single transformation that transforms shape A onto shape B. [2]
Coordinate grid, x from −10 to 10 and y from −7 to 7; shape A is an L-shape with vertices (1, 1), (2, 1), (2, 3), (3, 3), (3, 4), (1, 4); shape B is its mirror image with vertices (9, 1), (8, 1), (8, 3), (7, 3), (7, 4), (9, 4)
