## Whats That?

Prism: A polyhedron that has two bases that are parallel and the other faces are all rectangles.

Pyramid: A solid, formed by polygons, that has one base. The base can be any polygon, and the other faces are triangles.

Cylinder: A solid with two congruent circular bases that lie in parallel lines.

Cone: A solid with a circular base.

Sphere: A solid formed by all points in a space that are the same distance from a fixed point in the center.
