In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90- degree angles, or 100- gradian angles or right angles). All squares, therefore, have four right angles. All squares are parallelograms, rectangles and rhombi, but not all parallelograms, rectangles and rhombi are squares.
