How can we represent three-dimensional figures in only two dimensions?

1. How can we represent three-dimensional figures in only two dimensions?

2. In this lesson you will learn how to represent three-dimensional figures with nets by analyzing their faces and bases.

3. One-Dimensional Two-Dimensional ray rectangle line segment all polygons triangle line

4. A three-dimensional figure has a length, a width, and a height.

5. A net is a two-dimensional pattern of a three-dimensional figure, that can be folded to form the figure.

6. Identify the net that we could fold in order to create this 3D figure.

9. 2 triangle bases, 3 rectangle faces Match the 3D figure to the right with its appropriate net, below. A B C 2 triangle bases, 4 rectangle faces 4 triangle faces, 1 rectangle base 2 triangle bases, 3 rectangle faces

10. Match the 3D figure to the right with its appropriate net. C A B

11. In this lesson you have learned how to represent three-dimensional figures with nets, by analyzing their faces and bases.

12. Draw a net for this rectangular prism. • Faces? • 6 faces • 4 rectangles • 2 squares

13. Kennedy’s teacher asked her to draw the net of a rectangular prism. She drew the image, below. Explain to Kennedy what she did incorrectly.

14. A dodecahedron is a 3D solid with 12 flat faces. Can you draw the net for this dodecahedron?

15. Draw a net for a cube. Draw a net for this square pyramid.
