There is not a term for a polyhedron with 2 congruent faces. There are multiple polyhedra with 2 congruent faces.
Parallelogram prism
The ones that have are called 'squares'.
A cube.
Convex polygons with congruent sides and congruent angles are called regular polygons.
There is not a term for a polyhedron with 2 congruent faces. There are multiple polyhedra with 2 congruent faces.
A right prism is a polyhedron that has 2 congruent faces which are sometimes called bases.
A polyhedron that has two congruent faces is called a prism. It means that when it is cut at the cross-section, the shape is the same as its base.
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.
Some are regular and some are not . Regular rectangles are called squares. A square is a regular polygon because all of it's sides and angles are congruent. Oblong rectangles do not have all their sides congruent and so are not regular.
You can call it a hexahedron. A hexahedron is any polyhedron with 6 faces. A special kind of hexahedron having 6 faces made of congruent squares is called a cube.
A Prismthe faces are called bases

It is called a regular polygon. * * * * * Actually not. All its angles must also be congruent for it to be called regular.
That is called a regular polygon.
A regular octahedron.
