Properties of aProperties of a S UQ RA E A square is a quadrilateral and a four sided polygon.

It is defined as having equal sides and four interior angles equaling 90 degrees. Opposite side and angles are congruent. - Ex: A = B, C, & D<1 = <2, <3, & <4

Opposite sides are parallel. - Ex: A ll D, B ll C

To find the perimeter of a square add all of the sides together or multiply one side by 4.

Ex: X+X+X+X = perimeter of the square 4(X) = perimeter of a square

To find the area multiply one side of the square by another side of the square or square one side.

Ex: Y(Y) = area of the square Y^2 = area of the square

The diagonals of a square are congruent.

Each diagonal of a square is a perpendicular bisector of the other.

Angles between diagonals are all 90 degrees.

Hypercube In hyperbolic geometry, squares with right angles do not exist. Rather, squares in hyperbolic geometry have angles of less than right angles

In spherical geometry, a square is a polygon whose edges are great circle arcs of equal distance, which meet at equal angles. Unlike the square of plane geometry, the angles are larger than a right angle. .
