"WebThe defect of any polygonal figure on a unit sphere is equal to its area. Equivalently, the total turning angle of any polygonal figure on the sphere is equal to 2 Pi minus its area. The proof uses the result above concerning the sum of angles in a spherical triangle, after decomposing the polygonal figure into triangles and summing things up. " - Sphere in a triangle

In plane (Euclidean) geometry, the basic concepts are points and (straight) lines. In spherical geometry, the basic concepts are point and great circle. However, two great circles on a plane intersect in two antipodal points, unlike coplanar lines in Elliptic geometry. In the extrinsic 3-dimensional picture, a great circle is the intersection of the sphere with any plane through the center. In the intrinsic approach, a great circle is a geodesic; a shortest path betwee…
