They are closed 2-dimensional shapes.
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.
Circles and all regular polygons.
a polygon has all closed sides and no curved sides
Circles, some triangles, and irregular polygons
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.
Circles and all regular polygons.

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.
Prisms have polygons as bases whereas cylinders have circles as bases. In a way, a cylinder is like a circular prism.
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.'
The three types of polygons that can be the faces of a Platonic solid are A. equilateral triangles, B. regular pentagons, and E. squares. Platonic solids are characterized by having faces that are congruent regular polygons, and the only polygons that meet this criterion are those listed. Trapezoids and circles do not qualify as they are not regular polygons.
