For a regular polygon the internal angle between two sides is (180 - (360/n)) degrees where n is the number of sides. A regular polygon is one where all side lengths and angles are the same.

If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
1. Use a protractor. 2. If given the interior angle, use the linear pair postulate. (180-interior angle measure) 3. If given that the polygon is regular, divide 360 by the number of angles.
If it's a regular 9 sided polygon then each interior angle will measure 140 degrees.
Each interior angle of a regular polygon has a measure that is equal to one hundred and eighty degrees times two less than the number of sides in the polygon.
