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
Less than Perfect ABC ceased broadcasting the show, with the last episode broadcast on June 6, 2006. However, those episodes which were not broadcast in the US have been shown in other countries. The show joined Lifetime Television's lineup on June 1, 2009 in syndication. The network aired all 81 episodes, including the eight Season 4 episodes previously not broadcast in the US.
