## What is a non polygon?

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

## What is a polygon and what is not a polygon?

A polygon is a closed plane figure with three or more sides that are all straight. The following figure is not a polygon as it is not a closed figure. … A circle is not a polygon as it does not have straight sides.

## Why are the following figures not a polygon?

A polygon is a closed figure, formed by segments, and its sides do not cross. … The following figures are not polygons because they are not closed. The following figure is not a polygon because its sides cross in the middle.

## What does a polygon have to have?

A polygon is a closed figure where the sides are all line segments. Each side must intersect exactly two others sides but only at their endpoints. The sides must be noncollinear and have a common endpoint. A polygon is usually named after how many sides it has, a polygon with n-sides is called a n-gon.

## Which is not a regular polygon?

An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.

## What is the simplest polygon?

In geometry, a simple polygon /ˈpɒlɪɡɒn/ is a polygon that does not intersect itself and has no holes. That is, it is a flat shape consisting of straight, non-intersecting line segments or “sides” that are joined pairwise to form a single closed path. … The number of edges always equals the number of vertices.
