3. Exploring Three-Dimensional Figures Polyhedron – A closed three-dimensional figure made up of flat polygonal regions. The flat regions formed by the polygons and their interiors are called faces. Pairs of faces intersect in line segments called edges. Points where three or more edges intersect are called vertices.

4. Exploring Three-Dimensional Figures

5. Prism – a polyhedron with two congruent faces that are polygons contained in parallel planes. These two faces are called the bases. The other faces are called lateral faces and are shaped like parallelograms.

6. Exploring Three-Dimensional Figures Prisms are named by the shape of their bases. A regular prism is a cube.

7. Exploring Three-Dimensional Figures A polyhedron that has all faces except one intersecting at one point is a pyramid.

8. Exploring Three-Dimensional Figures A cylinder is a solid with congruent bases in a pair of parallel planes. However it is not a polyhedron. Why?

9. Exploring Three-Dimensional Figures A cone has a circular base and a vertex.

10. Exploring Three-Dimensional Figures A sphere is a set of points in space that are a given distance from a given point.
