- A bearing is a measure of direction which is measured in degrees clockwise from north.
- To measure the bearing from A to B, draw a vertical line up from A and label it as North.
- Then using a protractor measure the angle clockwise from this vertical line to the line between A and B.
- Bearings are always given as 3 digits:
- 120°, 030°, 009°.

Scale Factor and Enlargement
When a shape is enlarged, its lengths are all multiplied by S.
- for length
- for area - When a 2D shape is enlarged by a scale factor S, because all the lengths are multiplied by S, its area will be multiplied by S².
- for volume - When a 3D shape is enlarged by a scale factor S all the lengths are multiplied by S.
- The areas in the shape will be multiplied by S² and the volumes will be multiplied by S³.
