- What 3 things do you need to say to describe a rotation?
1. Where the centre of rotation is.
2. How much it is turned through.
3. Whether the rotation is clockwise or anticlockwise.
- Explain what centre of rotation means
The centre of rotation is the point of the grid that the shape turns around.
