WebA spherical triangle is any 3-sided region enclosed by sides that are arcs of great circles. If one of the corner angles is a right angle, the triangle is a spherical right triangle . In such a … WebDec 10, 2024 · 3 Answers. where a and b are the two legs of the right spherical triangle. Napier’s Rules do it easily. The Rule that helps you is sin b = tan a cot A, in other words, tan A = tan a sin b A = arctan ( tan a sin b), tan B = tan b sin a B = arctan ( tan b sin a), area = A + B − π 2. According to item 99 of the same source, E = A + B + C − ...
