I'm starting this review. My plan is to do two major passes through the article, first for prose, the second to verify the references. In general, all my comments will be suggestions which you can accept or reject as you see fit. -- RoySmith (talk) 21:05, 24 March 2021 (UTC)[reply]

Prose

Lead section

Regarding the ordering of the 6 formulation bullet-points, if this is commonly known as "Fermat's right triangle theorem", it seems odd that forulation is not the first bullet. Is there some logic to why they're in that order?

Regarding the accompanying figure, why the circles? I haven't yet read the rest of the article, so maybe that's explained later on, but at this point I'm just left wondering about them. The caption doesn't refer to them at all, hence the mystery.

Squares in arithmetic progression

"In 1225, Fibonacci was challenged to find". Who challenged him? I have a Monty Python-esqe mental image of some rogue leaping out of the shadows, sword drawn, demanding a proof. The sentence also parses ambiguously. I initially read it as listing several properties the triples should have: 1) they are equally spaced, 2) they form an arithmetic progression, and then started getting parse failures. I think (but I'm not sure), "which" is better than "that" here, but could also be left out completely. So, something like, "...for triples of equally spaced square numbers (i.e. an arithmetic progression), and for the spacing between these numbers (which he called a congruum)", although I'm not sure that's what you're trying to say.

(pausing here, I'll pick it up later, but this may be slow going)
