Question

Find the sum of the interior angle measures of the green polygon,

Then sum of the interior angle measures is

Answer 1

The sum of interior angles of given polygon is 900°

Explanation:

A regular polygon is a n-sided figure with n sides and the length of all sides is same.

In the diagram, we have a polygon with 7 sides.

The formula given is used to calculate the sum of interior angles of a polygon

`Sum\ of\ interior\ angles = (n-2)*180`

Here n is the number of sides of polygon

In the given polygon

n = 7

So,

`Sum = (7-2)*180 = 5*180 = 900`

Hence,

The sum of interior angles of given polygon is 900°
