Square

A square is a special type of quadrilateral, which is a polygon with four sides. What sets a square apart from other quadrilaterals is that all four of its sides are of equal length and all four of its angles are right angles (90 degrees).

The properties of a square include:

Four equal sides
Four right angles
Diagonals that are equal in length and bisect each other at right angles
Opposite sides that are parallel

The formula for finding the perimeter of a square is: P = 4s, where P represents the perimeter and s represents the length of one side.

The formula for finding the area of a square is: A = s^2, where A represents the area and s represents the length of one side.

With its unique properties and simple formulas for finding its perimeter and area, the square is an important concept in geometry and has many real-world applications.
