**scale factors**and scales**(ratios)**.**Scale Factor**: The constant factor by which all dimensions of an object are enlarged or reduced in a scale drawing.**Diagram above**: It shows the**enlargement**and the**reduction**of the square. When the square is**enlarged**, the area will increase from 36 units(squared) to 144 units(squared) and the side length will increase from 6 units to 12 units. In this case you are what is called**doubling (multiplying by 2)**and the**scale factor**is**2**. The**scale**for the enlargement will be**1:2**. When the square is**reduced**, you are basically**multiplying the bigger square by 1/2 or 0.5**. In this case you are**halving**and the**scale factor**is**1/2 or 0.5**. The**scale**for the reduction will be**2:1**.**Don't forget to do:**Chapter 4.1 (Page 130-135)
