Rotation Around a Point

A Rotation is… A rotation is a transformation that turns a figure around a fixed point called the center of rotation. A rotation is clockwise if its direction is the same as that of a clock hand. A rotation in the other direction is called counterclockwise. A complete rotation is 360˚.

A Ferris wheel makes a 90˚ rotation with ¼ turn.

Describe the Rotation in 2 ways. 120˚ Counter Clockwise 240˚ Clockwise

Describe the Rotation in 2 ways. 55˚ Clockwise 305˚ Counter Clockwise

Describe the Rotation in 2 ways. 175˚ Clockwise 185˚ Counter Clockwise

Describe the Rotation in 2 ways. 165˚ Counter Clockwise 195˚ Clockwise

Estimate the angle and direction of the rotation. About 85˚ Counter Clockwise

Estimate the angle and direction of the rotation. About 60˚ Counter Clockwise

Estimate the angle and direction of the rotation. About 140˚ Clockwise
