- Finding Scale Factor
To find a scale factor of an enlargement, you require two corresponding sides.
The scale factor of an enlargement is the ratio of the length of a side on a shape to the corresponding length on the other shape.
Scale factor = \( \frac{length\:on\:enlargement}{corresponding\:length\:on\:original} \)
- Scale factor bigger than 1 → it is an enlargement
- Scale factor smaller than 1 → it
