Bi-rectangular spherical triangle
WebThe area of a spherical triangle can also be calculated using the lengths of its sides, as in this Dr.Math link. The angle between two great circles is equal to the angle between the … WebAs we all know, the sum of angles of any planar triangle is equal to 180 degrees. However, for a spherical triangle, the sum of angles is always greater than 180 degrees. The difference between the sum of the spherical triangle angles and 180 degrees is called spherical excess . The task is to compute the spherical excess of a triangle with ...
