Examlex · Accepted Answer

The Answer is Suppose that Suppose that and are both be right angles. Then and . By the Protractor Postulate, . Then . But this last statement contradicts the fact that the sum of teh three interior angles of a triangle is exactly 180. Thus, the supposition must be false and it follows that and cannot both be right angles.
