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.
