Let's look at the geometric characteristics of a square. But first, please review the definition of Area Of Two-Dimensional Shapes, Exponents, Angle, and Right Angle.

- A square has some unique feature, all sides
are equal in length. For example, if one
**side (S)**is three inches in length, the other three sides are also three inches in length. - Another unique feature of a square, all sides are Perpendicular at the endpoint of each Line Segment.
- Special note, the side of a Square must be greater than zero.

**Area Of A Square Formula**

Formula = Side × Side =

Formula = Side^{2} =

Formula = S^{2}
