  1. A rotation has to have three elements… • A direction • Clockwise or anticlockwise • An angle to turn through • ¼ turn, ½ turn, 90°, 270° • A centre of rotation • Usually labelled c

  2. Rotate this shape 90° clockwise about the point c. c 90° clockwise

  3. Rotate this shape 180° anticlockwise about the point c. c 180° anticlockwise

  4. 4 3 2 A 1 0 -4 -3 -2 -1 0 1 2 3 4 -1 -2 Write down the coordinates of the shape. Describe the rotation Write down the new coordinates. What do you notice about the new and original coordinates? -3 -4

  5. 4 Draw a new shape in a different quadrant (not a square) Rotate it 90° clockwise. What is the connection between the original and new coordinates? Is the connection the same as before? 3 2 A 1 0 -4 -3 -2 -1 0 1 2 3 4 -1 -2 -3 -4

  6. Write down the coordinates of the shape Describe the rotation Write down the new coordinates. What do you notice about the new and original coordinates? 4 3 2 A 1 0 -4 -3 -2 -1 0 1 2 3 4 -1 -2 -3 -4

  7. 4 Draw a new shape in a different quadrant (not a square) Rotate it 180°. What is the connection between the original and new coordinates? Is the connection the same as before? 3 2 A 1 0 -4 -3 -2 -1 0 1 2 3 4 -1 -2 -3 -4
