The theorem that proves that △ABC and △DEF are similar is; SAS Similarity Theorem
From the given triangles △ABC and △DEF, we see that the corresponding angles ∠B and ∠E are equal.
Now, we can see that sides in △DEF are a third of the corresponding sides in △ABC.
Thus, we can say that AB is congruent to EF.
Therefore both triangles are congruent by SAS Similarity Theorem
