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
Rotate this shape 90° clockwise about the point c. c 90° clockwise
Rotate this shape 180° anticlockwise about the point c. c 180° anticlockwise
