Step1: Recall similarity - ratio property
For similar triangles, the ratios of corresponding sides are equal. Let's take problem 13 as an example. If $\triangle MNO\sim\triangle PQR$, then $\frac{MN}{PQ}=\frac{NO}{QR}=\frac{MO}{PR}$.
Step2: Identify corresponding sides
In problem 13, assume the side - length of $MN = 6$, $NO = 13$, and $QR = 44$. We want to find $PQ$. The ratio of corresponding sides gives us $\frac{MN}{PQ}=\frac{NO}{QR}$.
Step3: Set up and solve the proportion
Substitute the known values into the proportion: $\frac{6}{PQ}=\frac{13}{44}$. Cross - multiply to get $13\times PQ=6\times44$. Then $PQ=\frac{6\times44}{13}=\frac{264}{13}\approx20.3$.
For other problems (14 - 16), the same process is followed:
- Identify the similar triangles and the corresponding sides.
- Set up a proportion based on the ratio of corresponding sides.
- Cross - multiply and solve for the unknown side - length.
