What is polygons.

In geometry a polygon is a flat shape consisting of straight lines that are joined to form a closed chain or circuit.

A polygon is traditionally a plane figure that is bounded by a closed path, composed of a finite sequence of straight line segments (i.e., by a closed polygonal chain). These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices (singular: vertex) or corners. An n-gon is a polygon with n sides. The interior of the polygon is sometimes called its body. A polygon is a 2-dimensional example of the more general polytope in any number of dimensions.

The word "polygon" derives from the Greek πολύς (polús) "much", "many" and γωνία (gōnía) "corner" or "angle". (The word γόνυ gónu, with a short o, is unrelated and means "knee".) Today a polygon is more usually understood in terms of sides.

The basic geometrical notion has been adapted in various ways to suit particular purposes. Mathematicians are often concerned only with the closed polygonal chain and with simple polygons which do not self-intersect, and may define a polygon accordingly. Geometrically two edges meeting at a corner are required to form an angle that is not straight (180°); otherwise, the line segments will be considered parts of a single edge – however mathematically, such corners may sometimes be allowed. In fields relating to computation, the term polygon has taken on a slightly altered meaning derived from the way the shape is stored and manipulated in computer graphics (image generation). Some other generalizations of polygons are described below.

A polygon is a two-dimensional closed formed by three or more line segments.The line segments which make up the polygon are known as its sides and the point at which two line segments meet is called the vertices.No polygon can be formed by less than three line segments.Some of them are triangle, square, pentagon, hexagon, heptagon, octagon, nonagon, decagon.

A simple closed figure formed of three or more line segments is called a polygon. A polygon wit three sides is called a triangle . A polygon with four sides is called a quadrilateral . A polygon with five sides is called a pentagon. A polygon with six sides is called a hexagon . A polygon with seven sides is called a heptagon.
A polygon with 8 sides is a called a octagon
