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
Of Angels and Angles a world not of angels, but of angles where men speak of moral principles but act on power principles" The song is unique on the album in that it features only vocalist Colin Meloy with acoustic guitar accompaniment. Of Angels and Angles "Of Angels and Angles" is a track by The Decemberists off their album Picaresque. It is the eleventh and final song on the album.
