A square is a four-side geometric figure in which all sides are equal and all angles are right angles.


Introductory

A square is a a special quadrilateral in that it is regular.

Area

The area of a square can be found by squaring the square's side length - $A = s^2$.

Perimeter

The perimeter of square can be found by multiplying the square's side length by four - $P = 4s$.

Diagonal

The Diagonal of a square is obtained by the Pythagorean theorem. $D=\sqrt{s^2+s^2}=s\sqrt{2}$
