David Wishart commented on Randomly give two of hypotenuse, opposite, and adjacent side of a triangle 7 years, 5 months ago

I've done some trig questions recently that have triangles drawn in JSXGraph that could be useful here.

I've cobbled one into your question below, the scaling of the angle symbol is a bit ungainly as the set of triangles that I wrote it for had different proportions but the principle works.
