Geodesic Triangles

You can measure the area of geodesic triangles, and polygons on the surface of a sphere by measuring the angles at the vertexes. That is so cool. Yay Gauss-Bonnet!

I knew that on sphere the angles of triangles would add up to more than π, but I didn’t realize you could actually calculate area from them.
