Which statement is true given that triangle A'B'C' was formed after translating triangle ABC.

• ∠A ≅ ∠A' because corresponding angles are always congruent after a translation.

• ∠A ≅ A̅'B̅' because corresponding angles and line segments are always congruent after a translation.

• ∠A̅'B̅' ≅ ∠B̅C̅ because corresponding sides are always congruent after a translation.
