Your question is wrong because it has 12 sides and 54 diagonals
A 12-gon has 12 sides.
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.
12
It has 54 diagonals
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.
