Talk:Wallace–Bolyai–Gerwien theorem

Name clarification
I think the "William Wallace" who proved this theorem is different from Sir William Wallace. Are there any information about him? And what is the full name of Gerwien? --Hkpawn 15:15, 25 Dec 2004 (UTC)

It seems there's no proof that the firstname of Gerwien be Paul, see (https://hsm.stackexchange.com/a/12924). In fact, as indicated in this post, Gerwien could well be Karl Ludwig Gervien (https://de.wikipedia.org/wiki/Karl_Ludwig_Gervien) — Preceding unsigned comment added by 90.92.200.146 (talk) 07:31, 10 February 2023 (UTC)

Is the proof constructive?
Does there exist an algorithm for actually performing such reassembly for any two polygons, or does the proof merely show that it's possible without specifying how? - Sikon (talk) 10:03, 15 February 2010 (UTC)

Rework August 2015
I just thoroughly changed the article, according to my current knowledge and (hopefully) to follow wikipedia's guidelines on maths articles a bit more. I tried to preserve as much of the original content as possible, but that hasn't been easy. The History section has been copied verbatim, but I'd love to see some reference to it, possibly a slightly extended version. Without reference, I'm not sure how much I can believe of it, actually.

As for the rest of the article, I'm not entirely sure how much the sketch of the proof contributes to the article. It was previously in the introduction. What I did was move it and extend it to increase readability (hopefully). Since some major steps are omitted from the proof anyway, I'd say it could in fact be omitted. The notes on the proof in the next section, however, are still useful for those who do not know the proof. I would strongly recommend leaving those comments intact. — Preceding unsigned comment added by HSNie (talk • contribs) 23:41, 18 August 2015 (UTC)
