Books about: Non-fiction: Math: Pythagorean theorem proofs

[Justanotherbiblophile]

Allegedly, there are over 400 (I'm assuming unique, and non-derivative) proofs for the Pythagorean theorem (also, possibly the most for any mathematical formula).

I'd like a book that has all (or a vast majority) of them, and lays out the reasoning for them - and preferably the history of each proof.

f/Sparks:
"...via a series of proofs that increase in sophistication as centuries progress"

Reportedly, we do not have Pythagoras' own proof (if he ever did) of the theorem.

There are several books on the theorem:
The Pythagorean Theorem: A 4,000-Year History
The Pythagorean Theorem, Crown Jewel of Mathematics

Which I've not read yet; but I'd like the proofs - *NOT* discussion on the theorem's importance or history, or "spinoffs including trigonometry, puzzles, and pastimes." These books appear to have a selection of the proofs (ie: only a few - I'm guessing under 20).
