Question

Which polygon has an interior angle sum of 1080°?

Answer 1

The polygon with an interior angle sum of 1080° is an octagon or a polygon with 8 sides. We are given that the interior angle sum of our polygon

Explanation:

Sorry if it's wrong.

Answer 2

Explanation:

Remark

First of all, you need a regular polygon, otherwise the question can have all sorts of interior angles. The standard way to solve this is set up an equation that looks like this.

(n - 2)*180 = 1080 Divide by 180

(n - 2) = 1080/180

n - 2 = 6 Add 2 to both sides.

n = 6 + 2

n = 8

Conclusion

So an 8 sided figure has 8 interior angles that add up to 1080 if the 8 sided figure is regular.
