**PsyDAG**, Thursday, April 22, 2010 at 12:33pmFrom your description, you are not dealing with a parallelogram but rather a trapezoid. In a parallelogram, the top is parallel to the bottom, and the two sides are also parallel.

By "d2" do you mean "d squared"? (Online, d^2 = d squared.) Is there supposed to be an equal sign anywhere in your "Continuation"?

Repost your questions in clearer terms.
