Saccheri–Legendre theorem Saccheri–Legendre theorem In absolute geometry, the Saccheri–Legendre theorem states that the sum of the angles in a triangle is at most 180°. Absolute geometry is the geometry obtained from assuming all the axioms that lead to Euclidean geometry with the exception of the axiom that is equivalent to the parallel postulate of Euclid. The theorem is named after Giovanni Girolamo Saccheri and Adrien-Marie Legendre. The existence of at least one triangle with angle sum of 180 degrees in absolute geometry implies Euclid's parallel postulate. Similarly, the existence of at least one triangle with angle sum of less than 180 degrees
Silk Degrees "hit the R&B charts in a big way with the addictive, sly "Lowdown" [...] and expressed his love of smooth soul music almost as well on the appealing "What Can I Say."" However, Henderson stated that "Scaggs was essentially a pop/rocker, and in that area he has a considerable amount of fun." He concluded: "Though not remarkable, the ballads have more heart than most of the bland material dominating that format." On February 27, 2007, "Silk Degrees" was reissued by Legacy Records with three bonus tracks recorded live at the Greek Theatre on August 15, 1976. Silk Degrees Silk Degrees
