Since it has two sets of parallel sides and two pairs of congruent opposite sides, a rectangle has all the properties of a parallelogram.That’s why A rectangle is always a parallelogram. However, parallelograms are not always rectangles.

Are parallelograms sometimes rectangles?

A parallelogram is a quadrilateral with two sets of parallel sides. Since a square must be a quadrilateral with two sets of parallel sides, all squares are parallelograms. … A parallelogram is a rectangle. This is sometimes true.

Can a rectangle be a parallelogram?

Definition of Rectangle: A Parallelogram A rectangle whose four interior angles are congruent is called a rectangle. So, straight from the definition we see that any rectangle is a parallelogram with the additional property that all interior angles are congruent to each other.

When does a parallelogram have to be a rectangle?
