Sum of angles of a triangle to zero. For a spherical triangle, the sum of the angles is greater than 180° and can be up to 540°. Specifically, the sum of the angles is where "f" is the fraction of the sphere's area which is enclosed by the triangle. Note that spherical geometry does not satisfy several of Euclid's axioms (including the parallel postulate.) Angles between adjacent sides of a triangle are referred to as "interior" angles in Euclidean and other geometries. "Exterior" angles can be also defined, and the Euclidean triangle postulate can be formulated as the exterior angle theorem. One can also consider the
The Sum of Us (film) The Sum of Us (film) The Sum of Us is a 1994 Australian comedy-drama film version of the play "The Sum of Us" directed by Kevin Dowling and Geoff Burton and starring Russell Crowe and Jack Thompson. The screen adaptation mimics the play's device of breaking the fourth wall with direct to camera conversational asides by both Harry and Jeff.
