(4) Which shape is a parallelogram with 4 right angles?

A parallelogram with four right angles is known as a rectangle. This shape not only has opposite sides that are equal in length but also maintains its rectangular angles, making it a perfect candidate for both functional and aesthetic uses—from everything like windows and doors to your favorite table in the dining room! If you take a closer look, you'll find that the special case of a rectangle where all four sides are equal is called a square. Squares are not only beautiful in their symmetry but also have unique properties that make them fun in geometry, such as having equal diagonals and vibrant patterns in tiling!
