Lesson 8.2
Drawing Views of Rotated Objects
Get Started:
When an object is rotated horizontally, the axis of rotation is vertical.
The object may be rotated clockwise or counterclockwise.
When an object is rotated vertically, the axis of rotation is horizontal.
The object may be rotated toward you or away from you.

Investigate
You will need 6 linking cubes.
Use the linking cubes to build an object. Draw the front, top and side
views of the object.
Predict each view when the object is rotated...
• horizontally 90 degrees clockwise
• horizontally 90 degrees counterclockwise
• horizontally 270 degrees clockwise.

Connect:
Look at the object found on page 442.
Note how the object is rotated and how the views change.

Example 1:
Build the object found at the top of page 443.
It is rotated about the vertical axis.
Draw the front, top, and side views after a horizontal rotation of 270
degrees clockwise.

Example 2:
Build the object found at the top of page 443.
Draw the front, top, and side views after a horizontal rotation of 90
degrees counterclockwise.

Example 3:
Build the object found at the top of page 444.
It is rotated about the horizontal axis.
Draw the front, top, and side views after a vertical rotation of 90
degrees away from you.
