  1. Transformations:Part Three: Rotation

  2. Lesson Objectives • To be able to Rotate a shape around a given point

  3. What 3 pieces of information do you need to be able to rotate a shape?

  4. Rotate clockwise through 900

  5. Rotate this shape clockwise through 90 0 about the point c. c 90° clockwise

  6. Rotate this shape anticlockwise through 1800 about the point c. c 180° anticlockwise

  7. Rotations • A rotationturns a shape about a fixed point. • This point is called the centre of rotation. • You need three things to describe a rotation 1) the direction of the rotation (clockwise or anti-clockwise) 2) the angle (900, 1800, 2700) 3) the centre of rotation (always give as a co-ordinate)
