An interior angle of a regular octagon is 45 degrees. The exterior angles measure 315 degrees.
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Each exterior angle will measure 9 degrees
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
A polygon is "regular" (or equilateral) if all its sides are the same length and all its angles are the same angle. While a rectangle has 4 right angles, it does not have 4 sides that are equal length so the answer is irregular.

A rectangle has four angles inside it. Each of them is a right angle (measures 90 degrees).
A rectangle is a quadrilateral (four sided shape) with four right angles. Therefore, the measure of every angle is 90 deg.

the correct answer is 90
360 degrees, it could be a square or a rectangle
All of the angles are 90o.
