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
Kings of the Angles Like Offa, Freawine is made a descendant of Woden, and father of Wig, whose names were intruded into the pedigree of the kings of Bernicia when it was transferred to that of the kings of Wessex (ancestors of the kings of England). Wihtlæg, Wermund and Offa also appear in a long list of legendary Danish kings given by Saxo Grammaticus ("Gesta Danorum"). All other sources name them as kings of the Angles, though according to Matthew Paris ("Vitae duorum Offarum") Offa and his line personally ruled over the West Angles, implying that other branches of the tribe had their own
