G(-5, -2) and H(0, 0)

I suggest graphing to solve this one.

Since two of the points are given, all you have to do is find their opposites to the middle (D).

Example:
F(-2, 4) moves 2 up and 1 left from the middle, so to find the other vertex, do the opposite to the middle (2 down and 1 right). You end up with (0,0), which is point H.
