What is the name of a 12 sided shape?
dodecagon
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
What are the names of polygon from 11 to 20?
| Side | Name |

What does a 11 sided shape add up to?
1620 degrees
So, the sum of the interior angles of an 11-gon is 1620 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent).

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