Front

What is the relationship between the areas of two similar figures?

Back

The ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding side lengths.

Front

If the scale factor of two similar figures is 2:3, what does this mean?

Back

This means that for every 2 units in one figure, there are 3 corresponding units in the other figure.
