What is Definition of a square pyramid?
A polyhedron of which one face is a square, and the other faces are triangles with a common vertex.
Is a rectangle a polyhedron?
yes it is a polyhedron
Is a cuboid a polyhedron?
no a cuboid is not a polyhedron if it was it would have 9 faces
Why decahedron is not a regular polyhedron?
It is not a regular polyhedron because it has unequal sides
What is the difference between a polyhedron and a non polyhedron?
A polyhedron is a closed figure with several (planar) sides, and all its sides are planar. A non polyhedron does not have these properties, maybe it is not closed, maybe one or more of the sides is a curved surface. In some branches of topology the sides of a polyhedron cannot intersect each other.
What makes a polyhedron faceted?
The definition of polyhedron. If it was not faceted it would not be a polyhedron.
How does a 2-d polyhedron look?
A polyhedron, be definition, must be 3-dimensional. Therefore, there can be no such thing as a 2-d polyhedron
Are all sides of a polyhedron flat?
Yes, by definition.
Why is a three dimensional figure with curves surface is not a polyhedron?
It is so by definition.
Is every polyhedron a solid?
No. By definition a polyhedron has to have faces (flat surfaces), edges, and vertices. A sphere, hemisphere, and a cylinder are all solids but are not polyhedra.
What is the definition of a polyhendron?
If you mean polyhedron - it is solid figure having many faces
What is the definition of diagonals?
A diagonal is a line joining two nonconsecutive vertices of a polygon or polyhedron.
What is polyhedron's definition?
a 3d object made of 2d faces with all flat sides
What is Definition of a square pyramid?
A polyhedron of which one face is a square, and the other faces are triangles with a common vertex.
The edge of a polyhedron are the polygons which bound the polyhedron?
No, they are the faces of the polyhedron.
What is the definition of nonahedron?
A nonahedron is a nine faced polyhedron. A nonahedron is also known as a enneahedron. There are 2606 distinct convex nonahedra.
What does polyhedron mean in elementary school?
Start with the definition of a polygon. A polygon is a 2-dimensional (flat) surface all of whose boundaries are straight lines. Then, a polyhedron is a 3-dimensional (solid) object all of whose faces are polygons.
