Webthe angles of a spherical triangle must exceed 180 degrees. Many students find this concept intriguing. We shall prove that the area formula is A- 180 ' A _ 7rr2 (angle sum of triangle - 180) where the angles are measured in degrees and r is the radius of the sphere. The quantity "angle sum of triangle - 180" is called the excess of the triangle. Web9. sep 2024 · This note offers a probabilistic proof of Girard's angle excess formula for the area of a spherical triangle, based on the observation that an unbounded 3-dimensional convex cone, with single vertex at the origin, has only three kinds of 2-dimensional orthogonal projections: a 2-dimensional convex cone with one vertex, a 2-dimensional half …
