'Regular' means that all the sides on the polygon are the same length and all angles are the same size. On an irregular polygon, the sides can be different lengths and angles can be different sizes.
A square and a rectangle for example.
A regular polygon: a polygon with all the same size sides and angles. A polygon: can be different. EX: isosceles triangle. Hope this helps(: ~MICHIGAN NATIVE(:
The exterior angles of any polygon add up to 360. 360/15 = 24
It All depends how big it is
152.307692 repeating degrees
A square.
There is no way to work out the angles in a general polygon. The sum of the interior angles of a polygon, with n sides, is (n-2)*pi radians [or (n-2)*180 degrees]. Therefore, if you know the measure of n-1 angles, you can work out the size of the nth angle.Alternatively, if the polygon is one of the rare type - a regular polygon - then all its angles are equal. In that case, you can divided the above sum by n.
Quadrangle is the word used to denote a figure with four sides, regardless of the lengths or angles that make it up.

The regular polygon is congruent
The sum of the exterior angles of a polygon is 360°. There are the same number of exterior angles as there are sides. For a regular polygon all the angles are the same size: → number_of_sides × exterior_angle = 360° → exterior_angle = 360° ÷ number_of_sides → exterior_angle = 360° ÷ 5 = 72°
