take h, a and b to be the hypotenuse and the oposite two sides of a right-angled triangle.
Then:
Edit: Now all that's left to do is prove the trigonometric identity used without using pythagoras' theorem!

That is perfectly plausible.

My favourite geometric proof is the one that involves a square and four triangles making up a bigger square.
