Question

Find the size of each interior angle in a regular octagon

Answer 1

the formula for finding the measure of interior angles in a regular octagon is

(the number of sides the shape has - 2) * 180/ the number of sides

(8-2) *180/ 8

6*180/ 8 = 1080/8 = 135

The size of each interior angle in a regular octagon is 135°

Answer 2

To do this you divide 360 by 8 which equals 45
The exterior angle is 45°
So to find the interior angle you do 180-45=135
So one interior angle is 135°
