WebIn order to see why these laws are valid, we’ll have to look at three cases. For case 1, we’ll take the angle C to be obtuse. In case 2, angle C will be a right angle. In case 3, angle C will be acute. Case 1. For this case, we take angle C to be obtuse. This case has a wrinkle in it since the cosine of an obtuse angle is negative. WebThe Spherical Law of Cosines Suppose that a spherical triangle on the unit sphere has side lengths a, b and c, and let C denote the angle adjacent to sides a and b. Then (using radian measure): cos(c) =cos(a)cos(b) +sin(a)sin(b)cos(C). A spherical triangle is one enclosed by three great circles (each having radius 1 and common centre with the unit
