Nets A net is a pattern that you cut out and fold to form a 3 - dimensional figure.

Vocabulary Terms A cube is a prism with six congruent faces. Face

Vocabulary Terms An edge is a segment where two faces meet. Edge

Vocabulary Terms A vertex is a point where two sides of a polyhedron meet or a point opposite the base of a cone. Vertex

How many nets do you think you can come up with to form a cube? There are exactly eleven nets that will form a cube.

Nets for Pyramids have one base and lots of triangles. Sometimes they look like stars.

Vocabulary Terms Prism – a A cylinder with polygons for bases (faces). All prisms are special cases of cylinders. FACE

Vocabulary Terms In a prism, these faces are called bases. You name a prism by the shape of its bases. BASE

Special 3 -D Shapes Cylinder Sphere Cone

Sphere Every point on the surface of the sphere is the same distance from the center The normal definitions of faces, edges and vertices are not appropriate for a sphere.

Cone The vertex of the cone is opposite the circular base of a cone. The cone has a face, a vertex, and an edge (formed by the base and the lateral face).

Cylinder A prism with two congruent, parallel faces called bases. A cylinder has 2 faces (circular bases), edges and no vertices.
