What are two possible types of polyhedrons that has one face that is a triangle?
triangular prism and a pyramid
Why aren't cylinder cones and spheres polyhedrons?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Why aren't cylinders cones and spheres polyhedrons geometry?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
What are three-dimensional figures that are not polyhedrons?
A figure that has a curved face or curved edge.
Are prisims polyhedrons or not polyhedrons?
A prism is a polyhedron.
Who created polyhedrons?
No one. They are discoverable mathematical concepts.
Cones and polyhedrons both have only one base?
false
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.
Is an empty box a polyhedron. Do polyhedrons have to be solid?
Yes, an empty box is and No, polyhedrons don't have to be.
Cylinders and cones are just polyhedrons with circular bases?
False. Cylinders and cones are not just polyhedrons with circular bases.
Are not polyhedrons check all that apply.?
Polyhedrons are defined as three-dimensional shapes with flat polygonal faces, straight edges, and vertices. Therefore, objects that do not meet these criteria, such as spheres, cylinders, and cones, are not considered polyhedrons. Additionally, shapes with curved surfaces or those that are not fully enclosed do not qualify as polyhedrons.
