Spherical right triangle
WebA spherical triangle is defined when three planes pass through the surface of a sphere and through the sphere's center of volume. A spherical triangle has three surface angles and three central angles. In the figure, 'A', 'B', and 'C' label the surface angles while 'a', 'b', and 'c' label the central angles. WebSince any oblique spherical triangle can be described as either the sum or the difference of two right-angled spherical triangles, these rules provided a method for solving oblique...
