B.show both pairs of opposite sides are congruent
C.show one pair of opposite sides are parallel AND congruent
D.show both pairs of opposite sides are parallel

Respuesta :

Answer:

A

Step-by-step explanation:

Show that one pair of opposite sides is parallel and the other is not parallel

The answer will be option B .show both pairs of opposite sides are congruent

What is congruency?

The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.

The option B both pairs of opposite sides are congruent is not a method of proving that a quadrilateral is a parallelogram

Hence the answer will be option B .show both pairs of opposite sides are congruent
