Spherical polygon
WebGeometry of spherical triangle. Using the formula for the area of a spherical triangle, find and prove a formula relating the angle sum of a spherical polygon to its area. Area (spherical triangle) = R 2 ( α + β + γ − π) where α, β, γ are the interior angles. Let n be the number of vertices/sides of a polygon. 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].

WebNov 29, 2012 · It will also be 0 if the polygon is around the South Pole. We can use this information to determine exactly what a polygon contains. If the course delta sum is 360 we know that the polygon does not contain either pole. If the course delta sum is -360 it basically covers everything “outside” of itself. WebMar 24, 2024 · Spherical Geometry The study of figures on the surface of a sphere (such as the spherical triangle and spherical polygon ), as opposed to the type of geometry studied in plane geometry or solid geometry. In spherical geometry, straight lines are great circles, so any two lines meet in two points. There are also no parallel lines.
