WebSpherical triangle ABC is on the surface of a sphere as shown in the figures. Sides a, b, c (which are arcs of great circles) are measured by their angles subtended at center O of the sphere. A, B, C are the angles opposite sides a, b, c respectively. Area of the spherical triangle \displaystyle ABC = (A + B + C - \pi)R^2 ABC = (A+B +C −π)R2. WebStudents may find that the sides of their triangle are not straight lines. This is because on the surface of a sphere the shortest distance along the surface is not a straight line. It is actually a portion of what is called a Great Circle. Remember, a Great Circle is a circle on the surface of a sphere that has the center of the sphere as its ...

WebBasic properties. On the plane, the sum of the interior angles of any triangle is exactly 180°. On a sphere, however, the corresponding sum is always greater than 180° but also less than 540°. That is, 180° < α + β + γ < 540° in the diagram above. The positive quantity E = α + β + γ – 180° is called the spherical excess of the ...
