Area of a Parallelogram, Area = Base x Height, Geometric Proof

With these workings it is easy to see why the area of a parallelogram is its base multiplied by its height.

You'll also notice why the opposite sides of a parallelogram have angles that are equal.

This is an excellent resource for teachers who want to explain the reasoning why A=bh for a parallelogram or just mathematics enthusiasts who enjoy looking at proofs.

It may also be useful to mathematics artists who require a deeper understanding of specific formulas, for things such as vectors and computer graphics.
