  1. Three –Dimensional Figures -What is the difference between prisms and pyramids?

  2. What are three-dimensional figures? • A three-dimensional figure encloses a part of space. • In other words it can hold something (water, air, etc.) • It has Volume.

  3. Vertex Edge Faces Features of a 3-D figure • Face- the flat surface of a figure • Edge- formed by two faces of a 3-D figure sharing a side • Vertex (plural:vertices)- the point at which three or more edges meet

  4. 5 faces 8 edges 5 vertices 4 faces 6 edges 4 vertices Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B.

  5. 6 faces 12 edges 8 vertices 5 faces 9 edges 6 vertices Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B.

  6. Prism: Has at least three faces that are rectangles Has two congruent faces on the top and bottom called bases The shape of the base tells what type of prism the figure is Pyramid: Has at least three faces that are triangles Has only one base The shape of the base tells what type of pyramid the figure is Two main types of 3-D Figures

  7. Prisms Rectangular Prism Triangular Prism

  8. Pyramids Square Pyramid Triangular Pyramid

  9. Let’s PlayName that Figure!

  10. Rectangular Prism

  11. Triangular Prism

  12. Cube

  13. Square Pyramid

  14. Triangular Pyramid

  15. Polyhedron A 3-dimensional figure that has polygons as faces Polygons must have straight lines! Polyhedrons Not Polyhedrons
