## Rotating Shapes

This chapter explores rotating shapes. Itcovers rotating shapes around a coordinat grid, and describing rotations using angles and centres of rotations.

## Introduction

We shall look at transforming shapes around a grid using rotation. Below is a shape on a grid that we could use for this practice. To describe a rotation we need to identify the centre of rotation, how much it is turned for example angle such as 90 degrees, and whether the rotation is clockwise or anticlockwise## Describing rotations

Here we shall explore describing rotations. Below is a grid with shpe E rotated on to shape F. We can see that the angle of rotation is 90 degrees clockwise. The centre of rotation is at;## Direction of rotation

We describe an anticlock wise rotation as a positive rotation. The diagram below shows a positive rotation of 90° about 10. You can describe the rotation as a rotation of +90° about O. We call a clockwise rotation a negatve rotation. The diagram below shows a negative rotation of 90° about O. You could describe the rotation above +90 about O.## Introduction
