To find the exterior angle of any polygon, you can use the formula: 360 degrees divided by the number of sides. For an 8-sided polygon (octagon), the exterior angle would be 360 degrees divided by 8, which equals 45 degrees. This means each exterior angle of an octagon measures 45 degrees.

The sum of the exterior angle of any polygon is 360. So divide that by 8 in this case and each exterior angle has measure 360/8 or 45 degrees.
The angles of a 8 sided Polygon is 45 degrees.
Providing that it is a regular 8 sided octagon then each interior angle is 135 degrees
It is a regular 8 sided octagon whose interior angles are 135 degrees and its exterior angles are 45 degrees
8
2 methods: a: Interior angle = 180 - Exterior angle. The exterior angles of a regular n-sided polygon are equal to 360/n degrees. In this case n = 8 so Exterior angles are 45 degrees, making the interior angles 145 degrees; b: Total of interior angles of n-sided polygon is (2n -4) right angles, or 180n - 360 degrees. When n = 8, total of angles is 180 x 8 - 360 or 1080 degrees and each angle is 1080/8 or 145 degrees.
