Question

The polygons in each pair are similar. Find the scale factor of the smaller figure to the largerfigure. (Question 10)

Answer 1

Given the following general rule for the scale factor:

`\begin{gathered} Scale\text{ Factor:} \\ SF=\frac{\text{larger length}}{smaller\text{ length}} \end{gathered}`

So, we can take both bases of the triangles to get the following:

`SF=(20)/(16)=(5)/(4)`

therefore, the scale factor is 5/4
