WebThe spherical law of sines deals with triangles on a sphere, whose sides are arcs of great circles . Suppose the radius of the sphere is 1. Let a, b, and c be the lengths of the great-arcs that are the sides of the triangle. Because it is a unit sphere, a, b, and c are the angles at the center of the sphere subtended by those arcs, in radians.
