Quadrilateral ABCD is shown on the coordinate plane.

A figure shows a projector is placed 10 meters from a screen ABC with an angle of A 36 degrees projector and A`B`C` with an angle of A`36 degrees.
What needs to be proven to conclude that quadrilateral ABCD is a parallelogram?

A.
slope of AB = slope of BC and slope of CD = slope of DA
B.
slope of AB = slope of CD and slope of BC = slope of DA
C.
side length of BC = side length of DA and slope of DA × slope of AB = -1
D.
side length of AB = side length of CD and slope of BC × slope of CD = -1
