WebApr 9, 2024 · Polygons are two-dimensional geometric objects composed of points and straight lines connected together to close and form a single shape. Irregular polygons are polygons that have unequal angles and unequal sides, as opposed to regular polygons which are polygons that have equal sides and equal angles. As the concept of irregular … In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. Not every polygon has a circumscribed circle.

The spherical law of sines deals with triangles on a sphere, whose sides are arcs of great circles. Suppose the radius of the sphere is 1. Let a, b, and c be the lengths of the great-arcs that are the sides of the triangle. Because it is a unit sphere, a, b, and c are the angles at the center of the sphere subtended by those arcs, in radia… WebProblem.
