Answer:
The proportionality statement is [tex]\frac{DE}{ST}=\frac{DF}{SU}[/tex]
Step-by-step explanation:
Given that ΔDEF is similar to ΔSTU.
We have to write the proportionality that contains the sides ST and SU.
As we know the statement of proportionality, for the two shapes to be similar, the sides must be in proportion i.e
[tex]\frac{DE}{ST}=\frac{EF}{TU}=\frac{DF}{SU}[/tex]
we have to write the proportionality statement which contains ST and SU
[tex]\frac{DE}{ST}=\frac{DF}{SU}[/tex]
