3D Figures and Nets

3D Figures and Nets. Parts of a Polyhedron. Remember: A polyhedron is a 3D figure made up of polygons. Different Types of Faces. Remember that lateral means ‘side,’ so the lateral faces are the faces on the side of the polyhedron.

  1. 3D Figures andNets

  2. Parts of a Polyhedron Remember: A polyhedron is a 3D figure made up of polygons.

  3. Different Types of Faces Remember that lateral means ‘side,’ so the lateral facesare the faces on the side of the polyhedron. The shapes that define the polyhedron are also called bases. For example, the polyhedron below is called a triangular prism because the bases are triangles. The face that the polyhedron ‘stands on’ is called the base.

  4. Net A Net is how a 3D figure looks when it is unfolded into a 2D shape.

  5. Rectangular Prism 3 Dimensional Net 6 Faces 12 Edges 8 Vertices

  6. Triangular Prism 3 Dimensional Net 5 Faces 9 Edges 6 Vertices

  7. Square Prism (CUBE) 3 Dimensional Net 6 Faces 12 Edges 8 Vertices I’m a cube, too! IceCube

  8. Which one is incorrect?

  9. Triangular Pyramid 3 Dimensional Net 4 Faces 6 Edges 4 Vertices

  10. Square Pyramid 3 Dimensional Net 5 Faces 8 Edges 5 Vertices

  11. Is It a Prism or a Pyramid? The most common mistake students make is to mix up the prism and the pyramid. They call a triangular prism a triangular pyramid, and they call a triangular pyramid a triangular prism. Let’s avoid that mistake now… What is the difference between a prism and a pyramid? • The pyramid only has one base! • The prism has two bases! BASE
