Question

1- What is the formula for the sum of the interior angles of a polygon?

2- What is the interior angle sum of an octagon (8 Sides)

3-What is the measure of one interior angle of a hexagon (6 Sides)

4- What is the measure of one exterior angle of a regular 10-gon

Answer 1

\[\huge 180(n-2) \]

Answer 2

\(\bf \textit{sum of interior angles}=180(n-2)\qquad n=sides\)

Answer 3

2- to get it for an octagon, well, 8 sides, n = 8
3- 6 sides, n = 6
4- 10 sides, n = 10

Answer 4

So 180*6 for 2

Answer 5

yeap
180 * (8-2)
180 * 6

Answer 6

So 1080 is the answer
