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