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.
90 degrees

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
270
All of the angles are 90o.
360 degrees, it could be a square or a rectangle

An interior angle of a regular octagon is 45 degrees. The exterior angles measure 315 degrees.
