Talk:Solution of triangles

Merge with 'Triangle'[edit]

Why is this not included in the Triangle article? It should be merged into that article. 81.174.149.61 (talk) 13:24, 14 June 2011 (UTC)[reply]

‘Triangle’ is a big enough article as it is. If any merge is appropriate, merging with ‘Congruence (geometry)’ would be a better idea. —James Haigh (talk) 2013-04-14T14:18:00Z

Sources[edit]

The references www.mathsisfun.com and web.horacemann.org do not seem to be reliable sources in the Wikipedia sense of that term. Surely there are numerous textbooks that could be cited? Deltahedron (talk) 07:38, 27 January 2013 (UTC)[reply]

See for instance the lists at the end of pages:

Handbooks on plane trigonometry

Handbooks on spherical trigonometry

The SSA case is different from the others[edit]

The SSA case is not solvable in that it can lead to two distinct triangles. Why is it considered solvable in the article? If you are tempted to call it solvable, please explain why. After all, that AAA can have more than one solution is the stated reason that it is not considered solvable. Leegrc (talk) 13:06, 9 July 2015 (UTC)[reply]

A subset of the SSA case is solvable. I have added text to the effect that the SSA case has a unique solution only if the side length adjacent to the angle is shorter than the other side length. Leegrc (talk) 13:21, 9 July 2015 (UTC)[reply]

Perhaps spherical triangles should be split into a separate article[edit]

Even though solving spherical and planar triangles uses the same general approach, there's enough dissimilar about them, and enough extra material that can be added to each about history, connections to other subjects, etc. that it feels like they could be profitably split into two articles. A short summary could be left here and most of the material about spherical triangles could be moved to e.g. solution of spherical triangles, which can also be linked as the "main" article for Spherical trigonometry § Solution of triangles. Does anyone have objections to this idea? jacobolus (t) 00:55, 15 October 2022 (UTC)[reply]
