What is a 7 regular polyhedra?
There are only 5 regular polyhedra: those with 4, 6, 8, 12 and 20 faces. If you know of 7 polyhedra there may be a Fields Medal (the Nobel prize for mathematicians) for you!
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.
Which shapes all faces are flat?
Shapes with all flat faces are known as polyhedra. Common examples include cubes, tetrahedrons, and pyramids. These three-dimensional shapes are characterized by their flat polygonal faces, straight edges, and vertices where the faces meet. Regular polyhedra, like the Platonic solids, have congruent faces, while irregular polyhedra may have varied face shapes and sizes.
What is the relationship between faces edges vertices of polyhedra?
The Euler characteristic for simply connected polyhedra isF + V = E + 2 where F = # faces, V = # vertices and E = # edges.

What are the faces on a polyhedra called?
They are called "faces".
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.
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.
Which shapes all faces are flat?
Shapes with all flat faces are known as polyhedra. Common examples include cubes, tetrahedrons, and pyramids. These three-dimensional shapes are characterized by their flat polygonal faces, straight edges, and vertices where the faces meet. Regular polyhedra, like the Platonic solids, have congruent faces, while irregular polyhedra may have varied face shapes and sizes.
Can polyhedra objects roll?
Strictly speaking, no. But, as the number of faces increases, polyhedra can approximate cylinders or spheres and so can "roll".
Which 3d shapes have flat faces?
Polyhedra (singular = polyhedron).
Witch polyhedra has 12 regular pentagons as faces?
dodecahedron
What is a regular polyhedra with 12 regular pentagon faces?
dodecahedron
What are the names of the polyhedra that has 4 faces?
A tetrahedron or triangular pyramid.
What is the relationship between faces edges vertices of polyhedra?
The Euler characteristic for simply connected polyhedra isF + V = E + 2 where F = # faces, V = # vertices and E = # edges.
