Nets

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 edges meet. Vertex

How many nets do you think you can come up with to form a cube? 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.

Are these nets lined up with the right 3-D shape?

Vocabulary Terms Prism – a 3-D figure with two parallel and congruent polygon faces. The flat surfaces are called faces. FACE

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

Vertices Edges Faces The base has 3 sides.

Vertices Edges Faces The base has 4 sides.

Vertices Edges Faces The base has 5 sides.

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 point of the cone is directly above the centre of the circular base. The normal definitions of faces, corners and edges are not appropriate for a cone.

Cylinder A prism with a circular cross- section. The normal definitions of faces, edges and vertices are not appropriate for a cylinder.
