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.
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
