Snakes on a Plane and short film parody competitions. On July 6, 2006, the official "Snakes on a Plane" website started a promotional sweepstakes called "The #1 Fan King Cobra Sweepstakes". The contest made innovative use of the publicity-generating potential of the Internet, requiring contestants to post links on forums, blogs, and websites and collecting votes from the users of those sites. Many of the early fan-made trailers and later other viral videos and commercials circulated via YouTube, and captured media attention there with such titles as: "Cats on a Plane" (which was featured in Joel Siegel's review of "Snakes on a Plane" on
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
