Skill 01

2. Objective
HSG-CO.1a: Students are responsible for understanding and creating nets and drawings of three-dimensional figures.

3. Definitions
A net is a two-dimensional diagram that you can fold to form a three-dimensional figure.
An isometric drawing shows a corner view of a three-dimensional figure.
An orthographic drawing is a way to represent a three-dimensional figure using three separate views; top, front, and right.

4. Example 1: Identifying a solid from a net
a) The net folds into the cube. Which letters will be on top and front of the cube? D B A C E F E D C
E becomes the top
C becomes the front

5. Example 1: Identifying a solid from a net
b) The net folds into the cube. Which letters will be on top and right of the cube? D B A C E F E B C
E becomes the top
C becomes the right
