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 Hero episode received a Nielsen rating of 5.0/9. Zack Handlen of "The A.V. Club" gave the episode an A, saying: "Seeing Leela, Fry, and Bender work together as a team nearly always makes for something grand, and on the whole, “Less Than Hero” doesn’t disappoint. Its ambitions are modest, and it makes the most of them. Plus, it offers the rare chance to see super-heroes being ridiculous for no other reason than they want to. We could use more of that, really." Less Than Hero "Less Than Hero" is the fourth episode in the fourth season of the American animated television
