Web23 de dic. de 2024 · The Law of Sines and Laws(!) of Cosines apply to hyperbolic geometry and therefore must be reflected in any model of hyperbolic geometry. (That's what models do! :) The tricky part is translating model measurements into hyperbolic ones. The 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 radia…

There is one verytricky thing we have to look out for: Two possible answers.
