  1. Three-Dimensional Figures

  2. 3-D Figures • Cone • Cylinder • Prism • Pyramid • Sphere

  3. How are 3-D figures created?

  4. Space Figures • Move a rectangle through space – It creates a rectangular prism!

  5. Space Figures • Move a triangle through space – It makes a triangular prism!

  6. Space Figures • Move a circle through space – It makes a cylinder!

  7. Space Figures • Twirl (rotate) a triangle around one of its sides – It makes a cone!

  8. Space Figures • Twirl (rotate) a circle around its diameter – It makes a sphere!

  9. Ticket-out-the-door • What 3D figure is created when you…. • Translate a rectangle • Translate a circle • Rotate a rectangle • Translate a triangle • Rotate a triangle • Rotate a circle • Translate a square

  10. Cross-Sections EQ: How can I describe the cross-sections of solid figures?

  11. Vocabulary • Cross-section – a view of the inside of a 3D figure after it is sliced • Polyhedron – a 3D figure (a solid with flat faces) http://www.learner.org/channel/courses/learningmath/geometry/session9/part_c/index.html
