squares

Square- A Quadrilateral with four right angles and four congruent sides.

square properties
4 right angles the width is smaller then the length opposites are congruent lengths is a fourth of the width 4 equal sides 4 congruent sides diagonal bisect each other diagonals the same the parallelogram and the rhombus have same properites of the square The perimeter of a square whose sides have length t is p=4t and the area is a=4exponet2

In classical times, the second power was described in terms of the area of a square, as in the above formula. This led to the use of the term square to mean raising to the second power. perimeter = 4swhere s is the length of one side. See also Perimeter of a square. || The length of each diagonal is s√2 s is the length of any one side ||
 * Vertex || The vertex (plural: vertices) is a corner of the square. Every square has four vertices. ||
 * Perimeter || The distance around the square. All four sides are by definition the same length, so the perimeter is four times the length of one side, or:
 * Area || Like most quadrilaterals, the area is the length of one side times the perpendicular height. So in a square this is simply: area = s2where s is the length of one side. See also Area of a square. ||
 * Diagonals || Each diagonal of a square is the perpendicular bisector  of the other. That is, each cuts the other into two equal parts, and they cross and right angles (90°).
