For all you other k12 ppl dreading this ... the answer is D

Rojas · Answer 2

Correct choice is D

Step-by-step explanation:

A) This option is false, because diagonals AC and BD of the parallelogram heedn't be congruent.

B) This option is false, because if quadrilateral ABCD has two pairs of congruent sides, then this quadrilateral is kite (not parallelogram).

C) This option is false, because two pairs of opposite parallelogram's sides cannot be perpendicular.

D) This option is true, because parallelogram is a quadrilateral with two pairs of parallel opposite sides. So, if segments AB and CD have the same slope and segments AD and BC have the same slope, then AB║CD and AD║BC and ABCD is a parallelogram.
