Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.

The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.

Not too sure of the question but a square or a rhombus has opposite sides that are parallel and congruent in length
