  1. Rotation Around a Point

  2. 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˚.

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

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

  5. Describe the Rotation in 2 ways. 55˚ Clockwise 305˚ CounterClockwise

  6. Describe the Rotation in 2 ways. 175˚ Clockwise 185˚ CounterClockwise

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

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

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

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

  11. Rotation Activity
