Polygon names
The polygon is a closed plane figure composed by a non specified number of straight line
segments that join in pairs at their endpoints. A polygon is regular, when all the sides and internal angles are equal. On the contrary it is irregular.
The polygons are known by the number of sides. A polygon may also be named as n-gon.
Example:
1) 4-gon is a polygon with 4 sides;
2) 6-gon is a polygon with 6 sides.
3) 20-gon is a polygon with 20 sides.
