"Variation of Proof #6 - Pythagorean Theorem"

Alex,

In addition to the perhaps failed Calculus proof, I believe I have a variation of proof #6 which uses summing areas of the similar triangles, rather than using addition of the resulting proportions.

I have both variations in a single document. You can view it here:

Sorry I see a typo. The h = sqrt(xy)/c should only be h=sqrt(xy), but I believe the remainder of the document is accurate. I will make the change and upload a new link shortly.

Here is the corrected version of the aforementioned document:

After further review, I see that this is proof #19, which indeed is a variation of proof #6.
