A polyhedron with two congruent triangles. There are very many possible configurations.
A hexagonal prism.
rectangular prism
A cylinder is one example.
Yes, a polyhedron is only made up of one base which is bordered by straight lines. Each face is in fact a polygon, a closed shape in the flat 2-dimensional plane made up of points joined by straight lines.
A right prism is a polyhedron that has 2 congruent faces which are sometimes called bases.
A polyhedron that has 2 congruent faces is a PRISM. To be a prism, all the other sides (not including the 2 that are congruent) have to be 4-sided.

A hexagonal prism.
rectangular prism
A parallelogram or trapezoid.No!A parallelogram or a trapezoid are polygons (2-dimensional). A polyhedron, or 3-dimensional object, with parallel congruent bases is a prism.A prism. To give it fuller description, an "n-gonal prism" where the "n-gon" refers to the 2-d name of the bases.

Polyhedron* * * * *A polyhedron is a 3 dimensional figure, not its face! The face of a 3-d figure is a plane figure. It may be a polygon, of a circle or some irregular shape. The main requirement is that it is a plane (2-d) figure: if not, it is not usually called a face.
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
It is a prism with non-polygonal bases. The bases simply be two identically shaped "blobby" shapes.
An octahedron, which looks like 2 pyramids glued bottom to bottom.
