What does it mean if two figures are not scaled copies?

Back

It means that they do not have the same shape or their corresponding sides are not in proportion.

Front

How do you find the scale factor between two figures?

Back

To find the scale factor, divide the length of a side of the scaled copy by the length of the corresponding side of the original figure.
