In geometry, a polygon can be defined as a flat or plane, two-dimensional closed shape bounded with straight sides. It does not have curved sides. The sides of a polygon are also called its edges. The points where two sides meet are the vertices (or corners) of a polygon. Here are a few examples of polygons.
Polygons are defined as two-dimensional closed shapes that are formed by joining three or more line segments with each other. We tend to encounter polygons mostly while we learn about geometry.

Quadrilaterals. Quadrilateral just means "four sides". (quad means four, lateral means side). A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up). Polygon comes from Greek. Poly- means "many" and -gon means "angle".
Play with a polygon! Try adding or subtracting points. See the lengths, angles and coordinates, from triangles on up.
