Are all pyramids polyhedrons?
no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron * * * * * Yes they are.
What is a self dual polyhedron?
For every polyhedron, there is a dual which is a polyhedron that has:a face where the first had a vertex,a vertex where the first had a face,the same number of edges.A self-dual polyhedron is a polyhedron whose dual is the same shape.All pyramids, for example, are self-dual.
What polyhedron has 8 faces that are triangles?
An octahedron - which is like two rectangular pyramids whose bases have been stuck together.
Are pyramids polygons cylinders or prisms polyhendrons?
A polygon is a plane (2-dimensional) object bounded by straight lines. A polyhedron (not polyhendron!) is a solid (3-dimensional) object bounded by polygonal faces. So, pyramids and some prisms are polyhedra. A cylinder is a type of prism but, because two of its faces are circular, those faces are not polygons. As a result a cylinder is not a polyhedron.
You are a polyhedron All of your faces are the same All of your faces are equilateral trianglesI have eight facesWhat are you?
An octahedron formed by joining together (base-to-base) two square-based pyramids.
Are the great pyramids a polyhedron?
yes
Are all pyramids polyhedrons?
no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron * * * * * Yes they are.
Is a pyramid a polyhedra?
No. A pyramid is a polyhedron. Many pyramids are polyhedra.

What is a 10 sided polyhedron called?
An octahedron, which looks like 2 pyramids glued bottom to bottom.
What is a three-dimensional figure whose surfaces are polygons?
A polyhedron. Examples include pyramids and cubes.
What are pyramids in geometry?
Pyramids are a type of polyhedron that has a polygonal base with triangles extending from it to form an apex. The pyramids of Egypt would be examples of square pyramids because the bottom of them are squares. Likewise, you could have a pentagonal pyramid, hexagonal pyramid, pentagrammic pyramid etc.
What polyhedron has 5 corners and 6 faces?
A triangular dipyramid - two triangular pyramids stuck together, base-to-base.
What polyhedron has 8 faces that are triangles?
An octahedron - which is like two rectangular pyramids whose bases have been stuck together.
Is a pyramid a polyhedron?
It is. All sides of a geometric pyramid are flat - even stepped pyramids.
You are a polyhedron all of your faces are the same all of you faces are equilateral triangles you have eight faces?
that's easy its a triangle * * * * * That is such a nonsensical answer! A triangle is not even a polyhedron. The correct answer is an octahedron - two square based pyramids stuck together along their bases.
Are pyramids polygons cylinders or prisms polyhendrons?
A polygon is a plane (2-dimensional) object bounded by straight lines. A polyhedron (not polyhendron!) is a solid (3-dimensional) object bounded by polygonal faces. So, pyramids and some prisms are polyhedra. A cylinder is a type of prism but, because two of its faces are circular, those faces are not polygons. As a result a cylinder is not a polyhedron.
