Find the sum of the interior angles of the following: 5 Sides, 8 sides, 3 sides

The measurements would be 180 for 3 sides, 540 for 5 sides and 1080 for 8 sides.

You can find the sum of any regular figure using the interior angles formula. The formula is below for you.

(n - 2) * 180

In this equation, n is the number of sides. So the work is done below for you for each number of sides.

3 sides

(n - 2) * 180

(3 - 2) * 180

(1) * 180

180

5 Sides

(5 - 2) * 180

(3) * 180

540

8 Sides

(n - 2) * 180

(8 - 2) * 180

(6) * 180

1080
