2. Properties of a SU Q R AE 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 12 43 90 A B C D

3. T o 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 squar e XY X X X Y Y Y

4. 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. Diagonals of a Square To find the length of the diagonal, multiply one side by the square root of 2.

6. A Square is also a... Two – Dimensional 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..
