Question

Polygon ABCD will be dilated by a factor of 2 to produce polygon A′B′C′D′. The origin is the center of dilation. Which point will not represent a vertex on polygon A′B′C′D′ ? (­-2, -2) (4, 3) (0, 2) (4, -2)

Answer 1

Since the origin is the center of dilation. Take every vertex in the polygon ABCD and multiply it by 2 since the dilation factor is 2. It will result to polygon A'B'C'D'. Compare then the points given to the new points after dilation.
