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”.)

**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**.
