Question

polygon r is a scaled copy of polygon q. what scale factor takes polygon q to polygon r?

Explanation:

Step1: Recall scale - factor formula

The scale factor $k$ from polygon $Q$ to polygon $R$ is given by the ratio of the corresponding side - lengths of polygon $R$ to polygon $Q$.

Step2: Choose a pair of corresponding sides

Let's choose the side of length $0.3$ in polygon $Q$ and the corresponding side of length $0.15$ in polygon $R$.

Step3: Calculate the scale factor

$k=\frac{0.15}{0.3}=\frac{1}{2}=0.5$

Answer:

$0.5$
