A square is a polygon with four equal sides and four equal angles

A square is a polygon with four equal sides and four equal angles. In simple terms, it is a geometric shape that has all its sides of the same length and all its angles measuring 90 degrees (right angles).

The length of each side of a square is called its side length, and it can be denoted by the letter “s”. Since all sides of a square are equal, we can say that the perimeter of a square is equal to 4 times its side length, so the formula for the perimeter of a square is P = 4s.

Furthermore, a square has additional important properties. Firstly, the diagonals of a square are equal in length and bisect each other at right angles. Secondly, the area of a square is given by the square of its side length, so the formula for the area of a square is A = s^2. This means that if you know the side length of a square, you can easily calculate its area by multiplying the side length by itself.

Squares are commonly encountered in various real-life applications and are utilized in fields like architecture, construction, engineering, computer graphics, and mathematics.
