Three Dimensional Figures

Vocabulary to know: Face – a flat surface of a three dimensional figure. Edge – where two faces meet. Vertex – point where three or more edges meet.

Vertex Edge Face Base

Prism Definition: A three dimensional figure with two parallel, congruent bases. The base can be any polygon. The other faces must be parallelograms.

Pyramid Definition: A three dimensional figure with base, and faces made of triangles. The base can be any polygon.

Pyramid Definition: A three dimensional figure with base, and faces made of triangles. The base can be any polygon.

Naming a Prism or Pyramid Step 1 Identify and name the base Step 2 Identify if it is a prism or pyramid

Name the figure Rectangular Prism

Name the figure Triangular Prism

Name the figure Pentagonal Pyramid

Name the figure Cone

Name the figure Sphere

Name the figure Cylinder
