All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is:
Sum of Interior Angles = °
Each Angle (of a Regular Polygon) = °.
the interior angle of a regular polygon with
[a]8sides will be °
[b]20sides will be °
[c]24sides will be °

find the interior angle of a regular polygon with
[a]8 sides
-----
A different method:
Exterior angles are 360/n for n sides.
360/8 = 45 degs
Interior = 180 - Exterior
Interior = 180 - 45 = 135 degs.
=========================
[b]20 sides
[c]24 sides
