19 (a) Describe fully the single transformation that maps triangle A onto triangle B. [2]
(b) Reflect triangle A in the line x = 0. Label it C. [1]
(c) Enlarge triangle A with scale factor 1/2 through the origin. Label it D. [2]

(a) The transformation that maps triangle A onto triangle B is a translation. Triangle A is translated 6 units to the left and 4 units down. (b) To reflect triangle A in the line x = 0, flip the triangle over the y-axis. The coordinates of the reflected triangle C will have the same y-values as triangle A, but the x-values will be the opposite sign. (c) To enlarge triangle A with a scale factor of 1/2 through the origin, multiply each coordinate of triangle A by 1/2. The new coordinates will form triangle D.
