Polyhedron- is a three-dimensional solid figure in which each side is a flat surface.

Non-Polyhedra-if any surface is not flat.

Prism- has flat sides and the same cross section all along its length.

Pyramid- is made by connecting a base to an apex.

Cone- is made by rotating a triangle.

Cylinder-a solid geometric figure with straight parallel sides and a circular o section.

Sphere-denoting a structure or region of spherical form, esp. a region around the earth.

Torus-a surface or solid formed by rotating a closed curve, esp. a circle, around a line that lies in the same plane but does not intersect it.
