The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
135 Each interior angle of a regular octagon measures 135 degrees.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
Each interior angle measures 144 degrees
An interior angle of a regular octagon is 45 degrees. The exterior angles measure 315 degrees.
The sum of the interior angles add up to 7200 degrees
Each interior angle will measure 162 degrees
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
