...whose sides are arcs of great circles, and it is a well-known proposition of elementary geometry that the sum of the angles of a spherical triangle is greater than 1 80 degrees, and that the excess over 180 degrees is greater the larger the surface area of the triangle.... | |

...the only possible definition. It is interesting to note that in Euclidean three-dimensional geometry, the sum of the angles of a spherical triangle is greater than 180°, and the area of a spherical triangle is denned to be its "excess," that is, the sum of the degree... | |
