HEPPP ME PLEAS Martin wants to use coordinate geometry to prove that the opposite sides of a rectangle are congruent. He places parallelogram ABCD in the coordinate
plane so that A is (0,0), B is (a,0), Cis (a, b), and Dis (0, b).
What formula can he use to determine the distance from point D to point A?
A. (2-a)? +(6-0)2 = VB? -
= b
B. VO-0)2 +(6-0)2 - Vb? = b
C. (0-0) +(5-0)2 = 32
D. (2-a)? +(6-0)2 = 62
