it is an irregular quadrilateral
'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
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 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°
The answer is: Sum of Angles in a Regular Polygon = (Number of Sides - 2) * 180 Size of each of those angles = Sum of Angles / Number of Angles So for a Square it would be Sum = (4 - 2) * 180 = 360 Size of each angle = 360 / 4 = 90
The regular polygon is congruent
