There is no polygon with one side.
The perimeter of a polygon is the sum of the length of each of its sides. If the polygon is a regular polygon the you can calculate the perimeter as [number of sides] *[the length of one side]
An equilateral polygon is one in which all sides are equal
a "regular" one
A quadrilateral has 4 sides anda hexagon has 6 sides. So the polygon between them is the one that has 5 sides. That is the pentagon.
Hecatommyriagon is the 1 million sided polygon. A megagon is also a one million-sided polygon.

Polygon

the radius
A polygon that has 209 diagonals will have 22 sides and it's perfectly acceptable to call it a 22-agon.
