1.1 Nets and Drawings for Visualizing Geometry
3
Two vs. Three Dimensional
4
Net

• A net is a two-dimensional diagram that you can
  fold to form a three dimensional figure

5
Example

• Using this net, determine what letter would be on
  the top and front of the cube.

6
Drawing a net from a solid

• Example Make a net for the graham cracker box.
  Label the net with its dimensions

7
Isometric drawing

• An isometric drawing shows a corner view of a
  three dimensional figure.
• It allows you to see the top, front, and side of
  the figure

Isometric Paper

• Draw an isometric drawing of the figure below
• Step 1 Draw the front view
• Step 2 Start at each vertex and draw the right
  side view
• Step 3 Draw the back and top edges. Make sure
  all edges are parallel

9
Try it on your own!

• Draw an isometric drawing of the figure below

10
Orthographic Drawings

• An orthographic drawing is another way to
  represent a three dimensional figure.
• An orthographic drawing shows three separate
  views a top view, a front view, and a right side
  view (similar to an isometric drawing just taken
  apart)

11
Example
12
Try it on your own!

• Make an orthographic drawing for the isometric
  drawing

Think Pair - Share

• Spend 1 minute thinking about the difference
  between nets, isometric drawings, and
  orthographic drawings
• Spend 1 minute sharing what you thought about
  with the person next to you
• Share with the rest of the class! ?
