Visualizing Geometry Skill 01

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

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.

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? E A B C E D C D F E becomes the top C becomes the front

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? E A B C E D B C F E becomes the top C becomes the right

Example 2: Drawing a Net from a Solid a) What are two possible nets for the figure? Label net with dimensions. 20 cm 6 cm 14 cm 6 cm 20 cm 6 cm 14 cm 6 cm 20 cm 14 cm 6 cm

Example 2: Drawing a Net from a Solid b) What are two possible nets for the figure? Label net with dimensions. cm 24 10 cm 7 cm 24 cm 10 cm 7 cm 10 cm m c 24 10 cm

Example 3: Isometric Drawing a) What is an isometric drawing of the cube structure? t Fr on h g Ri t

Example 3: Isometric Drawing b) What is an isometric drawing of the cube structure? t Fr on h g Ri t
