Spherical right triangle
WebTheorem. The area of a spherical triangle ABC on a sphere of radius R is. SABC= (∠A+∠B+∠C−π)R2. (1) Incidentally, this formula shows that the sum of the angles of a spherical triangle must be greater than or equal to π, … WebApr 25, 2024 · We focus on the right spherical triangle A B C where C = ∠ A C B is right, a = 2 and b = 1. Length of hypotenuse c = A B ⌢ satisfies: cos c = cos a cos b = cos 1 cos 2 ≈ − 0.2248. With proper bounding, i.e. 0 < c < π, we conclude that c ≈ 1.798 and sin c ≈ 0.9744. Angle B = ∠ A B C, which is clearly obtuse, satisfies:
