Lemma 2 (Saccheri-Legendre Theorem) Assume Euclid’s Postulates I - IV (and all the facts as in (1) of the theorem) hold. Then the angle sum in every triangle is 180 .
WebTheorem 4.4 (Saccheri-Legendre): The sum of the degree measures of the three angles in any triangle is less than or equal to 180 degrees. Corollary 1: The sum of the degree measures of any two angles in a triangle is less than or equal to the degree measure of their remote exterior angle. WebSaccheri-Legendre Theorem: _ The sum of the angles of a triangle is at most 180 ∘. A triangle is an n -gon where n = 3. So to generalize I would want a formula for any n. Which …

Exercise 8.9 Prove the following corollary of Theorem 36 (Exterior Angle Theorem II). The sum of the measures of two angles in a triangle is less than or equal to the measure of their remote exterior WebSaccheri intended to show that the first and last could not happen, hence he would have found a proof for Euclid’s Fifth Axiom. He was able to show that the Hypothesis of the Obtuse Angle led to a contradiction. This result is now know as the Saccheri-Legendre Theorem (Theorem 7.3). He was unable to arrive at a contradiction when he looked at
