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 All Fears (film) a logical and lasting idea that would be universal." It has also been noted that a larger percent of profits stems from international audiences, and American filmmakers work to avoid alienating large segments of this customer base. Principal photography for "The Sum of All Fears" began on February 12, 2001 in Montreal, Quebec. A majority of the film was shot in Montreal, including the sequences at the football game that were shot in the city's Olympic Stadium. Additional filming was done at the Diefenbunker in Ottawa, Ontario. Production finished in June 2001. The interior scene of the aircraft carrier was
