Question

What scale factor was used to create triangle AA'B'C from AABC? Explain your reasoning.

Answer 1

Similarity ratio (also called scale factor) is the ratio of the lengths of the sides in two similar polygons. In this case:

`\begin{gathered} SF=\frac{10\text{ units}}{5\text{ units}} \\ SF=\text{ 2} \end{gathered}`
