Spherical triangle formula
WebTheorem 3 of McClure that the sum of angles of a triangle is ˇradians is false. The correct replacement for it is somewhat surprising. Theorem 104 (Gauss-Bonnet). If 4ABCis a spherical triangle, \A+ \B+ \C= ˇ+ area(4ABC) Corollary 1. Two congruent spherical triangles have the same area. 3 WebSides a, b, c (which are arcs of great circles) are measured by their angles subtended at center O of the sphere. A, B, C are the angles opposite sides a, b, c respectively. Area of the spherical triangle \displaystyle ABC = (A + B …
