 * The polygons.**

The polygons are geometric figures that are closed and you can see in two dimentions.

The word "Poligon" means "various sides", by this reason is that when we see the names of different polygons **__(__I think that here you must to place a comma(****,))** generally can noting that begin with the number of sides and ends with the word "gon"** (I think that you must to place a period) ** for **(If you placed a period, then the next word should begin with capital letters)** example, hexagon, heptagon, decagon and more. These figures should always have three or more sides.

The elements of a polygon are sides, vertices, diagonals and angles that can be internal or external. The most known types of polygons are regular polygons, irregular polygons, simple, convex, equilateral, equiangular and straight sides **(I** **think that this is a classification).**
