Answer 1

Option (3)

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.

`(AB)/(DE)=(BC)/(EF)=(AC)/(DF)`

Now from this relation,

`(BC)/(EF)=(AC)/(DF)`

`(DF)/(EF)=(AC)/(BC)`

Therefore, Option (3) will be the correct proportionality statement.
