A 12-gon has 12 sides.
12
It has 54 diagonals
the answer to this question is simple. any shape with more than 10 sides with two exceptions is the number of sides then gon. example: 12 sides= 12-gon, 13 sides=13-gon , etc.
An n-gon is the generic name for a polygon with nsides. It is an especially useful name for a polygon with a number of sides such that giving the polygon a name becomes complicated. For example, calling a shape with 54 sides a 54-gon is much simpler than calling the same shape a pentacontakaitetragon.
A 16-gon. You only name polygons up to a dodecagon (12 sides), excluding the 11-gon. After that, they are named by their number of sides with the suffix "-gon". Ex: 16 sides: 16-gon.
name of a polygon with 12 sides = dodecagon
12. Whatever number you say before '-gon' is referring to the number of sides in the shape. However, 12-gon (or 20-gon, or whatever) is not the official name of any polygon but is commonly used. the commonly used name is a do-decagon
Dodeka. (in Greek)
Dodecagon Dodeca = 12, gon = sides
Dodecagon Dodeca = 12, gon = sides
"a shape with twelve sides is called a 12-gon..... i promise its in my math book!" Officially its called a dodecagon. Often polygons with a lot of sides start being called x-gon where x is the number of sides.
