The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.The sum is always 360 degrees.

They are all 60 degrees.
Each exterior angle: 72 degrees Each interior angle: 108 degrees
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
It is: 180-exterior angle = interior angle

As for all polygons the exterior angles add up to 360 degrees
They are all 60 degrees.
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
360 degrees interior and exterior
Each exterior angle: 40 degrees Each interior angle: 140 degrees
Each exterior angle: 72 degrees Each interior angle: 108 degrees
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
It is: 160 degrees
Each interior angle is 140 degrees. Each exterior angle is 220 degrees.
For regular polygons, all the interior angles are the same measure, while the sum of the exterior angles is always 360 for any regular polygon. Use these facts and the fact that each interior/exterior angle pair has a sum of 180 to answer this question. 360 divided by 8 = 45. So each exterior angle of the figure measures 45. 180 - 45 = 135, so each interior angle measures 135 degrees.
