In geometry, a dodecagon or 12-gon is any twelve-sided polygon.

Then, What is a 11 sided shape called?

In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka “eleven” and â€“gon “corner”, is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim “eleven”.)

Considering this, What is a 13 sided shape called? In geometry, a tridecagon or triskaidecagon or 13-gon is a thirteen-sided polygon.

## How do you find the number of sides in a polygon?

Subtract the interior angle from 180. For example, if the interior angle was 165, subtracting it from 180 would yield 15. Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number of sides of the polygon.
