How to compute the sum of interior angles of the following polygons of undecagon

Answer 1

To Find :- the sum of interior angles of the following polygons of undecagon ?

Answer :-

we know that,

• A hendecagon also known as undecagon or endecagon is an 11 sided polygon.
• sum of interior angles of a polygon with n sides is = (n - 2) * 180° .

so, putting n = 11 , we get,

→ sum = (11 - 2) * 180°

→ sum = 9 * 180°

→ sum = 1620° (Ans.)

Hence, sum of interior angles of of undecagon polygon is 1620° .
