Nets of 3-D Figures. Objective:. Be able to draw or identify the net of a three-dimensional figure. Notes:.
E N D
Objective: • Be able to draw or identify the net of a three-dimensional figure.
Notes: • A net is flat pattern of a 3-dimensional figure. It can provide us with an easy way to analyze the different bases, faces, edges, and even dimensions of any space figure.
Watch: Watch a prism unfold to a net. Watch a pyramid unfold to a net.
Example 1: • Describe the net of a octagonal prism. list the shapes that make up the net (bases & lateral faces), and write the number of each shape used to construct it. • There are ___ bases, each in the shape of a _________________. • There are ___ lateral faces, each in the shape of a ________________.
Example 2: • Draw a net for each of the following three-dimensional figures. A) B)
Example 2: C) D)
Example 2: E) F)
