Quadrilateral proofs
Jun 15, 2022 · Figure 5.19.2 5.19. 2. We have determined there are four different ways to show a quadrilateral is a parallelogram in the x − y x − y plane. Let's check if a pair of opposite sides are congruent and parallel. First, find the length of AB A B and CD C D. AB = (−1 − 3)2 + (5 − 3)2− −−−−−−−−−−−−−−−√ ... For this, we must use the converses of our “precious” theorems: Theorem: If a quadrilateral is a parallelogram, then its opposite sides are congruent. If a quadrilateral is a parallelogram, then its diagonals bisect each other. If a quadrilateral is a parallelogram, then its opposite angles are congruent. Converse:

It was probably first formulated by the ancient Greeks.Here is a paragraph proof: A rhombus is a quadrilateral with four congruent sides, therefore opposite sides of a rhombus are congruent. Parallelogram theorem #2 converse states that “if the opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram”. Therefore, a rhombus is a parallelogram.

So for example, this interior angle right over here is larger than 180 degrees. And it's an interesting proof. Maybe I'll do a video.
