its a hectoctagon
A ceptagon
A megagon.
generally, with polygons with more than 12 sides, mathematicians just say number-gons, so a shape with 170 sides is a One-hundred seventy-gon.
the radius
A polygon that has 209 diagonals will have 22 sides and it's perfectly acceptable to call it a 22-agon.
Presumably, that would be a polygon with a hundred sides. Although it would probably be understood if you used it, "centi-" really means "one-hundredth" rather than "one hundred," so it would be better to call such a figure a "hectogon."
Each interior angle of a regular polygon has a measure that is equal to one hundred and eighty degrees times two less than the number of sides in the polygon.
There is no polygon with one side.
A polygon with 100,000 sides is called a "hectogon" or "100,000-gon." The prefix "hecto-" denotes a factor of one hundred, and in this case, it refers to the number of sides. While such polygons are primarily of theoretical interest, they can be studied in the context of geometry and mathematics.
There is not a name for such a polygon. A polygon with one million sides is called a megagon though..
A polygon is made of sides.
Just like a triangle is a polygon with 3 sides, A Quadrilateral(quad) is a polygon with 4 sides. Pentagon is a polygon with 5 sides and hexagon is one with 6 sides.
