It could be a cylinder or a cuboid
There are several cases: any 3 dimensional or more object. Since a polygon is defined as being confined to a single plane, any shape that violates the plane is not a polygon but may still have parallel bases. For cases in only 2 dimensions: Any object that has curves in addition to the parallel bases. A polygon's definition includes only straight sides. Finally, unclosed shapes can have 2 parallel bases with out being polygons even if in a single plane and made up of only straight line sides. A polygon must be closed.
No but a cylinder does have 2 parallel bases
Yes, every prism has 2 parallel bases.
a tapezium
Any polygon with 4 or more sides can have 2 parallel sides.
a parallelogram.

Yes, every prism has 2 parallel bases.
The parallel sides of a polygon are sides that are segments of parallel lines. A polygon need not have any parallel lines. A triangle, for example, is a polygon that cannot have parallel lines.
parallelogram
A parallelogram has 2 pairs of parallel sides.
A 3-sided polygon has 0 parallel sides. A 4-sided polygon can have 0, 2 or 4 parallel sides. A 5-sided polygon can have 0, 2, 3 or 4 parallel sides. In general, an n-sided polygon can have 0, 2, 3, ..., n-1, or n parallel sides where n>5. A polygon with n sides can have n pairs of parallel sides (if n is even) or (n-1)/2 pairs if n is odd AND greater than 3. But it need not have any.
A rectangle.
Parallelogram.
yes - one criterion of a polygon is being made up of only straight lines. polygons are also 2-dimensional. a cylinder is neither of these two things, as it is 3-dimensional (has length, width, and depth) and its two bases are circles, which are curved.
no its not a polygon
