Quadrilateral proofs.

This is kind of our tool kit. We have the side side side postulate, if the three sides are congruent, then the two triangles are congruent. We have side angle side, two sides and the angle in between are congruent, then the two triangles are congruent. We have ASA, two angles with a side in between. And then we have AAS, two angles and then a side.
