It's an irregular shape, but not an irregular polygon.
Addendum to the above answer:
Hopefully most of us will accept the above answer as correct, since it is correct for any practical or usefull purpose. However, if you are interested in pure theoretical geometry (which appears to be the case of the asker of the above question), consider the following.
A "polygon" is, by definition, a multiple-sided, multiple-angled plane figure. An oval, like a circle, at first glance, appears to have only one continuous side and no angles, so it does not qualify as a polygon.
However, if you had a polygon with 100 equal sides and 100 equal angles, it would look somewhat like a circle, and if it had 1000 it would look even more like a circle. If it had 10 million sides and angles, it would be, for practical purpose, a circle...even though it is still a polygon (a multiple-sided figure).
So a true circle could be considered to be a regular polygon with an infinite number of equal sides and a corresponding number of equal angles
An oval, on the other hand, would have an infinite number of sides, but would have ever-changing angles between them, making the oval an irregular polygon.
an irregular polygon is a polygon that is the opposite of a regular polygon in a regular polygon the sides are the same and the angles are the same and irregular is the opposite.
There are many shapes: Any regular polygon. An irregular polygon with an even number of sides in which the opposite sides and angles are equal. An irregular polygon with 3n sides where every third side is equal and every third angle is equal. and so on. A circle, ellipse, disc, oval
It is irregular as not all the sides have the same length.
an Irregular Polygon
There is no maximum number for a an irregular concave polygon. If it must be convex, then there is a maximum of 3.
A Polygon has 3 or more sides. It might be an irregular circle but that's it.
No, because it has no line segments

The definition of a irregular polygon is any polygon that is not a regular polygon.
an irregular polygon is a polygon that is the opposite of a regular polygon in a regular polygon the sides are the same and the angles are the same and irregular is the opposite.

A irregular nonagon is a polygon that is not a regular polygon.
If a polygon's lengths and angles are all equal it isn't an irregular polygon it's a regular polygon! :)
It is not a polygon at all, it is a polyhedron. It is irregular.
A square cannot be irregular though it is a polygon.
no
None, because an oval doesn't have sides and a polygon has 3 or more sides.
