The figure would be a prism. However, congruent polygons in parallel planes are called bases.
A triangular prism.
Obviously some kind of PRISM.
It need not be. A sphere, for example, has no rectangles nor polygons and no parallel planes either.
A three-dimensional figure formed by six parallelograms is called a Parallelepiped. A cube is one example and leads to the alternate definition of a polyhedron with six faces, each of which is a parallelogram.The opposite sides are in parallel planes.
It is a cylinder
A prism. The name of the prism usually reflects the polygonal shape of the bases eg triangular prism or rectangular prism.
Planes figures such as polygons are not solids. Solids are three-dimensional .
Yes. The opposite ends of any right prism consists of two congruent and parallel faces. Two planes are parallel if the vertical distance between them is always the same.
