Learn: the key idea

Each transformation needs specific information: translation needs a vector, rotation needs angle, direction and centre, reflection needs the mirror line, enlargement needs scale factor and centre.

Worked example

A shape turns 90° clockwise about the origin. Describe it fully.

Clock face showing 6 hours and 0 minutes
  1. 1Name the transformation: rotation.
  2. 2State angle and direction: 90° clockwise.
  3. 3State the centre: the origin (0, 0).

Answer: Rotation 90° clockwise about (0, 0)
