It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
The exterior angle sum of ANY plane polygon (ie 2-dimensional figure with straight sides) is 360 degrees.
Providing that it's a regular decagon then each exterior angle will measure 36 degrees
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.

The measure of the exterior angle of a convex octagon is indeterminate.
There are four exterior angles in a trapezoid, two on the top and two on the bottom.
180-interior angle = exterior angle
The measure of the exterior angle.
It is: 180-vertex angle = exterior angle
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
Usually, the measure of an exterior angle of a pentagon is greater.
Each exterior angle will measure 9 degrees
Providing that it's a regular decagon then each exterior angle will measure 36 degrees
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
The exterior angle sum of ANY plane polygon (ie 2-dimensional figure with straight sides) is 360 degrees.
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
