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.
The edge of a polyhedron are the polygons which bound the polyhedron?
No, they are the faces of the polyhedron.
