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).

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 1 10-6 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 1 10-6 Three-Dimensional Figures

Additional Example 2A: Naming Three- Dimensional Figures Name the three-dimensional figure represented by the object. The figure is __________ a polyhedron. There is a ____________ surface.The figure represents a _________________. There are two congruent, parallel bases. The bases are ___________. Course 1 10-6 Three-Dimensional Figures
11
Additional Example 2B: Naming Three- Dimensional Figures Name the three-dimensional figure represented by the object. The figure _____ a polyhedron.All the faces are flat and are polygons. The figure is a ___________________ pyramid.There is one base and the other faces are triangles that meet at a point, so the figure is a pyramid. The base is a _______________. Course 1 10-6 Three-Dimensional Figures
12
Additional Example 2C: Naming Three- Dimensional Figures Name the three-dimensional figure represented by the object. The figure ______ a polyhedron.All the faces are flat and are polygons. The figure is a ______________________ prism.There are two congruent, parallel bases, so the figure is a prism. The bases are __________________. Course 1 10-6 Three-Dimensional Figures
