Answer: A parallelogram is a rectangle.
Step-by-step explanation:
This is always true. Â Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides. ... A parallelogram is a rectangle.
