Rotating shapes: |
Grid squares can be used to show shapes,
made up of squares.
We can rotate the shape, turning through a number of a right angles. First we need to choose a point which the shape can turn around. |
|||||||||
| If you turn the shape though a quarter turn, it has gone through 1 right angle. |  |

 |
If it is turned through a half turn,
it has gone through 2 right angles.
If it moves through another right angle, so it has gone through 3 right angles. If it goes through another right angle, it has gone back to where it started - it has gone through 4 right angles. |
