New blog post: Angles of arc-triangles, https://11011110.github.io/blog/2021/07/10/angles-arc-triangles.html

If you make a non-self-crossing shape bounded by three circular arcs, what triples of interior angles can you get at its three corners? For straight sides you would get a sum of angles equal to \(\pi\) but for arc-triangles the constraints are less simple.
