Quadrilaterals.
It is a 15 sided polygon
It depends on what type of polygon it is and how many angles it has.
a regular polygon
Hexagon
hexagon which has 6 sides
A quadrilateral.
A nonagon aka enneagon
It is a 15 sided polygon
any polygon
It depends on what type of polygon it is and how many angles it has.
If you mean interior angles of 2800 degrees then no such polygon exist because one of its sides woud not meet up with another side.
a regular polygon
Hexagon
Yes, a regular polygon is a type of polygon where all the sides and angles are equal.

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.
That will depend on what type of isogon it is because an isogon is the name given to any regular polygon whose interior angles are equal.But in the general: (n-2)*180 = sum of interior of any polygon whereas 'n' is the number of sides of the polygon.
