A polygon is a geometric figure in two dimensions with three or more
sides. The name comes from two Greek words,
*
poly,
*
meaning "many,"

and
*
gon,
*
meaning "angle." A polygon always has as many angles as it
has sides. And in general, polygons are named to indicate the number of
sides or angles they contain. Thus, a hexagon has six (
*
hexa-
*
means "six") sides and six angles.

*
Side:
*
Any one of the straight lines that make up the polygon.

*
Vertex:
*
A point where any two of the sides of a polygon meet to form an angle.

*
Angle:
*
A figure formed by the intersection of two sides.

*
Diagonal:
*
A line that joins any two nonadjacent (not next to each other) vertices.

*
Perimeter:
*
The sum of the length of all sides.

*
Area:
*
The space enclosed within the polygon.

*
Equilateral:
*
A polygon in which all sides are equal in length.

*
Equiangular:
*
A polygon in which all angles are the same size.

*
Regular:
*
A polygon that is both equilateral and equiangular.

The most common kinds of polygons include:

*
Parallelogram:
*
A quadrilateral (four-sided figure) in which both pairs of sides are
parallel and equal.

*
Rhombus:
*
A parallelogram in which all four sides are equal.

*
Rectangle:
*
A parallelogram in which all angles are right angles.

*
Square:
*
A rectangle in which all four sides are equal.

this articles is helpful in math because when you have work you can solve it only 30 seconds or lower than 30 seconds

this is great webpage for everyone, aside from being helpful to researchers it will makes easier to anyone who wants to learn, however still it needs improve the diagrams samples.
