What are the five regular polyhedra?
The five regular polyhedra are Tetrahedron, Hexahedron(cube), octahedron, dodecahedron and Icosahedron.
How are rectangular prism and triangular prism alike?
They are polyhedra, with several rectangular faces, and with two identical and parallel bases.
Which 3d shapes have flat faces?
Polyhedra (singular = polyhedron).
How many faces does a pyramid prism have?
faces i geuss * * * * * A pyramid and a prism are two different kinds of polyhedra. There cannot be a pyramid prism just as there cannot be a square triangle!
What 3D shape has some triangular faces?
There are infinitely many polyhedra with one or more triangular faces.
What shape has five sides and five faces?
A side is the same thing as a face. A quadrilateral based pyramid or triangular prism are the two possible polyhedra.
What are similarities for a rectangular pyramid and triangular prism?
They are both polyhedra with five faces.
What are the faces on a polyhedra called?
They are called "faces".
For what polyhedra does Euler's formula Faces plus vertices equals edges plus two apply?
It applies to simply connected convex polyhedra.
What kind of polyhedra has more faces than vertices?
Bipyramids are a class of polyhedra with more faces than vertices.
What shapes have identicle faces?
Regular polyhedra have identical faces.
What shape has two opposite identical faces?
A cube, a dodecahedron, an icosahedron amongst regular polyhedra. Many irregular polyhedra, including a prism.
How a triangular prism and a pyramid are alike?
They are both polyhedra. They have traingular bases. They have at most five faces. They have at most six vertices.
Is a polyhedron with two parallel congruent faces?
There are infinitely many such polyhedra. A regular dodecahedron, for example.
How are rectangular prism and triangular prism alike?
They are polyhedra, with several rectangular faces, and with two identical and parallel bases.
How are triangular prism and rectangular prism alike?
They are polyhedra, with several rectangular faces, and with two identical and parallel bases.
Which 3 dimensional figure has faces that are always congruent and the same shape?
There are a few families of polyhedra with identical faces. There are none whose faces have 6 or more sides. There is no special name for polyhedra whose faces are pentagons or pentagrams. A dodecahedron is an example. If coplanar faces are disallowed, the only polyhedron with quadrilateral faces are the cube and rhombohedron. There are infinitely many polyhedra with equilateral triangular faces: the tetrahedron, octahedron and icosahedron are examples.
