no
None, because an oval doesn't have sides and a polygon has 3 or more sides.
A circle or oval.
A polygon is usually defined as a plane figure bounded by straight line segments. Any figure which does not correspond to this definition would be a non-polygon. For example, triangles, rectangles, squares, and even star shapes are called polygons. A circle, semicircle or oval is not a polygon. The have curved boundaries.
there cannot be a one sided polygon as a polygon is defined as a 2-dimentional shape, which has area, and is enclosed by straight sides. Thus a polygon must have at least 3 sides so that it can enclose an area. Perhaps the question is supposed to be more along the lines of what 2-dimentional shape has only one side? this would be a circle

A circle or oval.
A Polygon has 3 or more sides. It might be an irregular circle but that's it.
No. A polygon is a shape bounded by STRAIGHT lines.
It is a circle or an oval shape.
No because an octagon is an 8 sided polygon
A shape very close to a circle or an oval.
Normally you just add the sides of a polygon. If it's a rounded polygon (ex:circle, oval, etc), then there is a different formula. (ex:circle=pi*r squared)
Any closed figure formed by a set of straight linesegments is a polygon. If the segments are curved such as in a circle or oval, the closed figure is not a polygon.

oval of revolution would be the exact math term for it. Doctor Chuck
