Practice Quiz on Properties of polygons
See notes below
For any polygon, the exterior angles add up to 360 degrees.
For a regular or equilateral polygon, a single exterior angle will be 360 divided by the number of exterior angles.
For the interior angles, the sum of these angles will be (n-2)180.
For a regular or equilateral polygon, one way to find a single interior angle will be the sum above divided by the number of angles. Another way to find this is the to find a single exterior angle and subtract this number from 180 since the interior and exterior angle make a linear pair.
