# What is a non-polygon?

##### 1 Answer

*Non-polygon* is a geometric object that does not conform the definition of *polygon* (see below).

#### Explanation:

*Polygon* is a geometric object that consists of certain finite number of segments (let's label them

(a) they are sequentially connected into a closed figure, that is the end of

(b) all the points of coincidence mentioned above are different;

(c) there are no other intersection points among these segments.

In addition: Note that polygons are two-dimensional, (planar) and that the segments are straight lines, so any shape which includes an arc is not a polygon. (A circle is therefore not a polygon).

A geometric object that does not satisfy one or more of these three conditions IS NOT a *polygon* and you can name it a *non-polygon*.
