A 20 sided polygon is an 'icosagon'
Icosahedron is a 20 sided polygon.
A 20 sided polygon
A 20-sided polygon is called an icosagon. In geometry, a polygon with n sides has n vertices. Therefore, a 20-sided polygon would have 20 vertices. Each vertex represents a point where two sides of the polygon intersect.
Polygons with 61 to 69 sides are referred to by specific names based on the number of sides they have. A 61-sided polygon is called a "hexacontakaihenagon," a 62-sided polygon is a "hexacontakaihenagon," a 63-sided polygon is a "hexacontatrihenagon," a 64-sided polygon is a "hexacontatetragon," a 65-sided polygon is a "hexacontapentagon," a 66-sided polygon is a "hexacontaxihexagon," a 67-sided polygon is a "hexacontaseptagon," an 68-sided polygon is a "hexacontaoctagon," and a 69-sided polygon is a "hexacontanovagon." These names are derived from Greek numeral prefixes combined with the suffix "-gon."
N-gon is the name of 13-20 sided polygon.
Duodecagon <--wrong... a duodecagon is a 12-sided polygon. icosagon is a 20 sided polygon.
Shapes with 13 to 20 sides are known as polygons. Specifically, a 13-sided polygon is called a tridecagon, a 14-sided polygon is called a tetrakaidecagon, a 15-sided polygon is called a pentadecagon, a 16-sided polygon is called a hexadecagon, a 17-sided polygon is called a heptadecagon, an 18-sided polygon is called an octadecagon, a 19-sided polygon is called an enneadecagon, and a 20-sided polygon is called an icosagon.

A 20 sided polygon is an 'icosagon'
A polygon with 20 sides is called an icosagon, while a polygon with 29 sides is called an enneakaikaienneagon. These names are derived from the Greek numerical prefixes "icosi-" and "enneakaikaiennea-", which mean twenty and twenty-nine, respectively. The suffix "-gon" is added to indicate a polygon.
