Nets and Drawings for
Visualizing Geometry
Problem 1: Identifying a Solid From a Net
Net: a two-dimensional diagram that you
can fold to form a 3-D figure. It shows all
of the surfaces of a figure in one view
EXAMPLE:
The net shown below folds into the
cube beside it. Which letters will be on
the top and the front of the cube?
The net shown below folds into the
cube beside it. Which letters will be on
the top and right side of the cube?
Problem 2: Drawing a Net From a Solid
What is a net for the graham cracker box
shown? Label the net with its dimensions
What is a net for the figure shown?
Label the net with its dimensions.
Problem 3: Isometric Drawing
Isometric Drawing: shows a corner view of
a 3-D figure. It allows you to see the top,
front, and side of the figure
EXAMPLE:
What is an isometric drawing of the
cube structure shown?

cube structure shown?
Problem 4: Orthographic Drawing
Orthographic Drawing: another way to
represent a 3-D figure. It shows three
separate views: a top view, front view, and
a right-side view
