3-74.

Solve for the missing lengths in the sets of similar figures below.

1. $ΔABC\simΔOPQ$

$\frac{6}{f} = \frac{4}{6}$

$f=9$

2. $EFGHI\sim STUVW$

$\frac{24}{20} = \frac{g}{15}$

3. $JKLM\sim WXYZ$

Use the same method as parts (a) and (b).

4. Specify a sequence of transformations to map $ΔABC$ onto $ΔOPQ$ in part (a).
