Question

E, F, and H are three of the vertices of rectangle EFGH on the coordinate plane. What are the coordinates of G, the fourth vertex of the rectangle?

Answer 1

if ABCD and EFGH are similar, then you should be able to line up corresponding points (for example, A corresponds to E, B corresponds to F). if they're different sizes, you should then dilate one of them so that they are the exact same size

Answer 2

The coordinates of G are (-5, -5)
