WebbA common application of the sine rule is to determine the triangle \( ABC\) given some of its sides and angles. The ambiguous case refers to scenarios where there are 2 distinct triangles that satisfy such a configuration. This occurs when we are given the angle-side-side, as shown in the diagram below:
WebbThere is a unified formulation of law of sines which is true in all 3 constant curvature geometries (Euclidean, spherical, hyperbolic): l(a) sinα = l(b) sinβ = l(c) sinγ, where l(r) is the circumference of a circle of radius r. Is there a ‘uniform’ proof that works in all 3 geometries?
