A square is a quadrilateral geometric shape that consists of four equal sides and four equal angles. The area of a square can be obtained by evaluating the numerical product of its two sides. The perimeter of the square is four times the magnitude of the side.

**Properties of a Square **

1. The sum of all the angles of a quadrilateral is equal to 360°, and all the angles of a square are equal in magnitude; therefore, the angles formed between the two adjacent sides of a square is equal to 90°.

2. The opposite sides of a square are parallel to each other.

3. The two diagonals formed by joining the opposite corners of a square are equal in length and have the value √2 times the magnitude of the side of the square.

4. The diagonals bisect each other at an angle of 90°.
