What is the definition of polyhedron?
A polygon has many sides whereas a polyhedron has many faces as for example a pyramid
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.
Is a triangle a polyhedron?
NO!!! A triangle is a 2-dimensional shape of three sides; archaically a 'trigon'. A polyhedron is a 3-dimensional solid of many sides.
Is the Empire State Building a polyhedron?
yes because a polyhedron is a flat shape with straight sides, for example a cube or a triangular prism.
What are the example of a pyramid?
A polyhedron with a polygonal base and triangles for sides.
Is a dodecahedron an example of a polyhedron?
Yes
What has 8 corners and 6 faces in a polyhedron?
a cube, for example
What shape has face's edge's vertexes?
A polyhedron as for example a pyramid
What is another name for a three dimensional shape?
a polyhedron * * * * * That is only if it is bounded by plane faces. A sphere, for example, is a three dimensional shape but is not a polyhedron: it is a solid shape.
Is a cone a example of a pyramid?
No, a pyramid is a polyhedron with flat faces and straight edges.
What is a non polyhedron with 2 congruent and parallel bases?
A cylinder is one example.
How many vertices's does a convex polyhedron have if it has 14 faces and 24 edges?
Using Euler's Polyhedron formula V+F-E=2, givenF=14 and E=24, we have V=12.The polyhedron has 12 vertices.This assumes a genus-0 polyhedron. An example would be the hexagonal antiprism, a polyhedron having two hexagonal faces and 12 triangular faces.
