A ___________________ is a three- dimensional object, or solid figure, with flat surfaces, called ____________, that are polygons. When two faces of a three-dimensional figure share a side, they form an __________. On a three-dimensional figure, a point at which three or more edges meet is a _____________ (plural: vertices). Course Three-Dimensional Figures

Additional Example 1: Identifying Faces, Edges, and Vertices Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B. Course Three-Dimensional Figures

A _____________ is a polyhedron with two congruent, parallel ____________, and other faces that are all parallelograms. A prism is named for the shape of its bases. A ______________ also has two congruent, parallel bases, but bases of a cylinder are circular. A cylinder is not a polyhedron because not every surface is a polygon. Course Three-Dimensional Figures

A ______________ has one polygon shaped base, and the other faces are triangles that come to a point. A pyramid is named for the shape of its base. A ____________ has a circular base and a curved surface that comes to a point. A cones is not a polyhedron because not every surface is a polygon. Course Three-Dimensional Figures

The point of a cone is called its ________________. Helpful Hint Course Three-Dimensional Figures
