Which statement is not always true for a parallelogram?
VARVARA [1.3K]
<h3>Answer: B. Diagonals are congruent.</h3>

Explanation:

If the diagonals are congruent, then we'd have a rectangle. Any rectangle is a parallelogram, but not the other way around.

If we had a non-rectangular parallelogram, with none of the angles 90 degrees, then the diagonals will not be the same length.

Choices A, C and D are true for any parallelogram (rectangle or not).
