Answer:

B) Use the slope formula to prove the slopes of the diagonals are opposite reciprocals.

Step-by-step explanation:

A distance formula is used to find the length of a line segment. Knowing diagonal lengths cannot tell you they are perpendicular, eliminating choices C and D.

Diagonals of a quadrilateral are never parallel, so choice A makes no sense.

The slopes of the diagonals of a quadrilateral will be opposite reciprocals if the diagonals are perpendicular. The slope formula can be used to show that is the case. Choice B is the appropriate answer.
