Length Scale Factor

The length scale factor is the ratio between the lengths of two objects.

$\text{Length Scale Factor} = \dfrac{\text{Length of Object 1}}{\text{Length of Object 2}}$

It can also be written with a colon as separator.

$\text{Length of Object 1}:\text{Length of Object 2}$

For example, consider two segments: segment $\overline{A}$ is $2\text{ ft}$ and segment $\overline{B}$ is $4\text{ ft}.$ $\dfrac{A}{B} = \dfrac{2}{4} = 0.5$ The scale factor is $0.5$ because $\overline{A}$ is half the length of $\overline{B}.$
