Prove that in Euclidean geometry (so using the 5th postulate) the sum of the angles in a triangle is equal to a straight angle. (For convenience you can use 180° as the measure of a straight angle. As we discussed in class you cannot assume that there is a single, consistent measure for the sum of the angles.)
