The question is based on the false impression that there are only two polyhedra. There are, in fact, infinitely many.
A polyhedron, be definition, must be 3-dimensional. Therefore, there can be no such thing as a 2-d polyhedron
There is not a term for a polyhedron with 2 congruent faces. There are multiple polyhedra with 2 congruent faces.
For a simply connected polyhedron,Faces + Vertices = Edges + 2
A net is a 2 dimensional representation of a 3 dimensional polyhedron
A right prism is a polyhedron that has 2 congruent faces which are sometimes called bases.
Nope - A polygon is a flat, 2-dimensional shape. A Polyhedron is a 3-dimensional shape.
A polyhedron with two congruent triangles. There are very many possible configurations.
A polyhedron is a 2 dimensional object. To have fasce it would have to be at least 3 dimensional. If you want to know what is a polyhedron with 4 sides, it's a quadrilateral THAT'S NOT QUITE RIGHT - actually it's completely false. Sorry, Ratty, a polyhedron is a 3 dimensional figure. Polygon refers to 2 dimensional figures. A pyramid with a triangular base is a polyhedron with 4 faces.
How many sides does it have altogether? If it just has the 2 angles and side and 3 corners, there is no polyhedron with that discription.
A tetrahedron
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.
No polyhedron has five sides as a pentagon and a hexagon has six sides
