how did the word polygon originate
A polygon with vertices (and sides) is known as an-gon. A polygon for which the only points of the plane belonging to two polygon edges of are the polygon vertices is said to be a simple polygon. If all sides and angles are equivalent, the polygon is called regular. Polygons can be convex, concave, or star. The word polygon derives from the Greek poly, meaning many, and gonia, meaning angle.. The most familiar type of polygon is the regular polygon, which is a convex polygon with equal sides lengths and angles.
