Question

PART 1: Quadrilateral  with the following information:

1. 
2. 
3. 
4. 

Prove:  is a rectangle. PART 2: Given the situation above, why is it not possible to prove that  is a square?

Answer 1

I'm terrible with proofs, but since P is congruent to S and a quadrilateral has supplementary opposite angles, use substituion to show that P and R and/or Q and S are congruent, thus you must have four 90 degree angles.

I bet you can figure out why we can't prove it's a square!

Answer 2

This shape is not a rectangle or a square; it's a quad. This shape has no right angles.
