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

Explanation:

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#.
