okenn nan
deklarasyon ki anwo yo pa kòrek.
triang abc se konjwen ak triang def.
triang abc se similè ak triang def
triang abc egal ak triang def

Explanation:

The problem involves triangle similarity (since $\triangle ABC \sim \triangle DEF$ is given). The option "Triang ABC se similè ak triang DEF" translates to "Triangle ABC is similar to triangle DEF", which matches the similarity notation. Other options: "konjwen" (congruent) is stricter, "egal" (equal) is incorrect for similarity, and the first option is about a correct declaration but not the relation.

Answer:

Triang ABC se similè ak triang DEF (the third option in the list of blue boxes, reading "Triang ABC se similè ak triang DEF")
