Don't you mean "coords," or (better yet) "coordinates?"
Look at line DG as an example.  It's vertical.  If you rotate the whole figure clockwise, then line DG becomes the horiz. line D'G.'  G' would have the coordinates (-1,-1), and D' (5,-1).  Plot these points G' and D' and see whether or not you agree.
