Name a parallelogram with four congruent sides and four right angles.

A parallelogram is a quadrilateral whose opposite sides are parallel and equal in length.

Answer: Square is a parallelogram with four congruent sides and four right angles.

Let's find the parallelogram with the above properties.

Explanation: 

Condition 1: Parallelograms with four congruent sides are Square and Rhombus.

Condition 2: Parallelograms with four right angles are Square and Rectangle.

Square is the only parallelogram that satisfies both the conditions of having four congruent sides and four right angles.

Therefore, a square is a parallelogram with four congruent sides and 4 right angles.
