Solids having flat surfaces that form into polygons are polyhedrons true or false?
true
All polyhedrons are prisms or pyramids.?
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
Do polyhedrons have right angles?
not all
Why are three dimensional figures with a curved surface not polyhedrons?
Three-dimensional figures with a curved surface are not considered polyhedrons because polyhedrons are defined as solids with flat polygonal faces, straight edges, and vertices. Curved surfaces lack these flat faces and straight edges, which are essential characteristics of polyhedrons. Examples of shapes with curved surfaces include spheres and cylinders, which do not fit the definition of a polyhedron. Thus, the presence of curved surfaces distinguishes these figures from polyhedra.
What are all the shapes that are not polygons?
They are 3 dimensional objects such a s polyhedrons.

What are all the four sided polyhedrons?
tetrahedrons
What has bases and sides that are polygons?
All polyhedrons.
What are the properties of polyhedrons?
Polyhedrons are three-dimensional geometric shapes with flat polygonal faces, straight edges, and vertices. They are characterized by their number of faces, vertices, and edges, which are related by Euler's formula: ( V - E + F = 2 ), where ( V ) is vertices, ( E ) is edges, and ( F ) is faces. Polyhedrons can be classified into regular (Platonic solids, where all faces are identical) and irregular types. Their faces can vary in shape, but they are always formed by connecting edges at vertices.
What is the collective name of a cube tetrahedron dodecahedron and a octahedron?
Polygons ( means many sides). They are called solids or polyhedrons; they exist in three dimensions and not two.

Is it true that all polyhedrons are cubes?
No. Not even all hexahedrons are cubes.
Are prisims polyhedrons or not polyhedrons?
A prism is a polyhedron.
What are all the shapes that are not polygons?
They are 3 dimensional objects such a s polyhedrons.
