WebSpherical convexity is defined for any set of points. A set of points on the sphere is said to be spherically convex, if for any two points, the geodesic joining them lies entirely in the set. If the points are not contained within an open hemisphere, the convex hull is defined to be the whole sphere [Grima and Marquez, p. 47]. WebSince the area of a spherical triangle is proportional to its excess, the area of each polygon is \(n\pi r^2\left(\frac2n+\frac2k-1\right)\text{,}\) using , where the constant of …
