Answer:
Option (3)
Step-by-step explanation:
From the given figure,
Two triangles ΔABC and ΔDEF are similar.
ΔABC ~ ΔDEF
By the definition of similarity of two triangles, corresponding sides of the similar triangles are in the same ratio.
[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]
Now from this relation,
[tex]\frac{BC}{EF}=\frac{AC}{DF}[/tex]
[tex]\frac{DF}{EF}=\frac{AC}{BC}[/tex]
Therefore, Option (3) will be the correct proportionality statement.
