  1. Nets

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

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

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

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

  6. 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.

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

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

  15. Fun with Prisms

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

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

  18. Triangular Prism Vertices 6 Edges 9 Faces 5 The base has 3 sides.

  19. Rectangular Prism The base has 4 sides. Vertices 8 Edges 12 Faces 6

  20. Pentagonal Prism The base has 5 sides. Vertices 10 Edges 15 Faces 7

  22. Fun with Pyramids

  23. A pyramidis a cone with a polygon for a base. All faces joining the vertex are triangles. They are named by the shape of the base. vertex vertex vertex base base base

  24. Triangular Pyramid Vertices 4 Edges 6 Faces The base has 3 sides. 4

  25. Square Pyramid The base has 4 sides. Vertices 5 Edges 8 Faces 5

  26. Pentagonal Pyramid Vertices The base has 5 sides. 6 Edges 10 Faces 6

  29. Special 3-D Shapes Cylinder Sphere Cone

  30. 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.

  31. 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).

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