Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed using trigonometric functions. On the sphere, geodesics are great circles. Spherical trigonometry is of great importance for calculations in astronomy, geodesy, and navigation. WebFeb 20, 2024 · These triangular wedges are actually triangles I studied in non-Euclidean geometry because their angle measure is above 180 degrees, where the two congruent … WebEach triangle has 3 midpoints along 3 of it's edges. We call these m_ {01}, m_ {02}, m_ {12} m01,m02,m12. We then lift these midpoints so they touch the surface of the sphere — in other words we normalise them. We can then form 4 new triangles from the midpoints and the existing vertices. It's easier to see this on a diagram: bramwell tovey urban runway
