They are closed 2-dimensional shapes.
Circles and all regular polygons.
Circles, some triangles, and irregular polygons
Your quesion makes no sense. Please elaborate, and i will do my best to provide an answer. You need to tell me what your are comparing polygons to. Ex: What are 4 thing polygons and CIRCLES have in common. your sentence lacks that.
Prisms have polygons as bases whereas cylinders have circles as bases. In a way, a cylinder is like a circular prism.
no straight sides
yes. polygons are closed shapes with no curves. i.e. circles are not polygons, squares are, triangles are, ect
A circle is not a polygon, so no.

There are 20.5 + 6 + 9 = 20 (Neither circles nor unclosed linear shapes are polygons.)
Circles, some triangles, and irregular polygons
A polygon is a two-dimensional shape enclosed by lines only, not curves. So triangles, squares, rectangles, and octagons are examples of polygons. Circles, ellipses, and annuli are some shapes that are not polygons.

Some examples of polygons include circles, triangles, squares, rectangles, pentagons, and hexagons. These are examples of 'simple polygons,' in that none of the lines overlap and intersect each other, such as in a pentagram, which is a 'star polygon.'
A polyhedron is a 3 dimensional figure made of polygons. A cylinder is made of two circles and a rectangle around the middle. Since circles are not considered polygons (don't have straight edges), a cylinder cannot be a polyhedron. I just had a discussion about this with my math students today.
