Rectangle Properties

Answer 1

Opp. sides Parallel 
opp. sides cong. 
opp. angles cong. 
diagonals bisect 
consective interior angles supp. 
DIAGONALS CONG
All angles are right angles

(Parallelogram with diagonals cong. And four right angles)

Question 2

How to Determine if Coordinate Quadrilateral is a Rectangle?

Answer 2

STEP A: SEE IF PARALLELOGRAM
1) Distance Formula- are opp. sides cong?
2) Slope Formular: are opp slopes the same? (Parallel)
3) Midpoint Form: do diagonals have the same midpoint?
STEP B: SEE IF RECTANGLE
1) use distance form. To see if diagonals are cong.
