All of the polygons because they don't have depth
It depends on the shape. The top of a pyramid will be a point (the apex). The top (and bottom) of a prism or an antiprism will be congruent polygons.
A polyhedron.
A cube is not a polygon. Polygons are 2-dimensional figures and a cube is 3-dimensional.
Yes. Parallelograms are flat shapes (polygons). 3-dimensional forms are polyhedrons.
No, a cube is a 3 dimensional shape. All polygons are 2 dimensional.
A polyhedron is a 3-dimensional shape whose faces are all polygons.
It is a 3-dimensional shape whose faces are all polygons.
There are infinitely many polyhedra that can be made from two different polygons.
All of the polygons because they don't have depth
They are polygons which have 3 or more line segments
It depends on the shape. The top of a pyramid will be a point (the apex). The top (and bottom) of a prism or an antiprism will be congruent polygons.
Polygons !
No.
Most 2 dimensional shapes (all polygons) have 3 or more vertices. Most 3-dimensional shapes (polyhedra) have 4 or more vertices.

A cube is not a polygon. Polygons are 2-dimensional figures and a cube is 3-dimensional.
