### Transformations:Part Three: Rotation

Lesson Objectives
• To be able to Rotate a shape around a given point

c

180° anticlockwise

Rotations
• A rotationturns a shape about a fixed point.
• This point is called the centre of rotation.
• You need three things to describe a rotation

1) the direction of the rotation (clockwise or anti-clockwise)

2) the angle (900, 1800, 2700)

3) the centre of rotation (always give as a co-ordinate)
