The sides of a square are all congruent (the same length.)

The angles of a square are all congruent (the same size and measure.)

Opposite angles of a square are congruent.
Opposite sides of a square are congruent.
Opposite sides of a square are parallel.

To find the perimeter of a square, just add up all the lengths of the sides.

To find the area of a square, multiply the lengths of two sides together.

To find the length of the diagonal of a square, multiply the length of one side by the square root of 2

The diagonals of a square intersect (cross) in a 90 degree angle. This means that the diagonals of a square are perpendicular.
The diagonals of a square are the same length (congruent).

A square is a rectangle, parallelogram, trapezoid, and rhombus.
