False. Cylinders and cones are not just polyhedrons with circular bases.
Cylinders and cones are not considered polyhedrons because they do not have flat faces, which is a defining characteristic of polyhedrons. Polyhedrons are three-dimensional shapes made up of flat surfaces, while cylinders and cones have curved surfaces. Additionally, polyhedrons have straight edges where faces meet, whereas cylinders and cones have curved edges. Therefore, cylinders and cones are classified as curved surfaces rather than polyhedrons.
true
Pentagons can be symmetrical, but are not always so.
The space it occupies isn't symmetrical.
A prism is a polyhedron.
No. Polyhedrons are any shape with multiple sides. A triangle and a prism are just two different kinds of polyhedrons.
Yes, an empty box is and No, polyhedrons don't have to be.
False. Cylinders and cones are not just polyhedrons with circular bases.
polyhedrons need flat face and edges, corners which cylinder cones don't have.
