WebA triangle on a sphere is defined as the intersecting area of three great circles. Unlike a plane where the interior angles of a triangle sum to pi radians (180 degrees), on a sphere the interior angles sum to more than pi. As the sphere becomes large compared to the triangle then the the sum of the internal angles approach pi. http://paulbourke.net/geometry/circlesphere/
