A parallelogram with four congruent sides and four right angles is known as a square. In geometry, a square is a specific type of quadrilateral that meets two important criteria: all sides are of equal length (congruent), and all interior angles are right angles (90 degrees).
This unique combination of properties gives the square its distinctive shape and allows it to possess equal opposite sides and angles, which are characteristic of all parallelograms. Additionally, the diagonals of a square bisect each other at right angles and are of equal length, further emphasizing its symmetry.
Understanding the properties of squares can be very helpful in geometry, as they serve as a fundamental building block for more complex shapes and concepts.
