Determine whether the polygons with the given vertices are similar.
Quadrilateral ABCD with vertices A(–3, 3), B(0, 3), C(0, 1), D(–3, 1)
and quadrilateral EFGH with vertices E(2, –8), F(8, –8), G(8, –12), H(2, –12)

a little inspection (or drawing) will reveal that
ABCD is a rectangle with width=3 and height=2
EFGH is a rectangle with width=6 and height=4
Since the width and height have both been scaled by 2, the two rectangles are similar.
