1. Where is the centre of rotation
2. How much is it turned through. (1/4 or 1/2 turn or an angle)
3. Whether the rotation is anticlockwise or clockwise.
Explain what centre of rotation mean
The centre of rotation is the coordinates that show from where the shape will be turned from.
Now use these 3 things to describe the rotation on Page 1 of the myimaths lesson (i.e. describe the rotation of the triangle)
The centre of rotation of the triangle is 1,1.
The triangle has been turned 90º and is clockwise
