2 &Given:&& PQRS is a rectangle &Prove:&& PR≅QS
Let's use variables to name the coordinates of Q, R, and S.
These are just example variables, so your variable choices may differ.
2 &Given:&& PQRS is a rectangle &Prove:&& PR≅QS
Substitute ( 0,0) & ( s,q)
Subtract terms
Substitute ( 0,q) & ( s,0)
Subtract terms
(- a)^2=a^2
