Step-by-step explanation:

Step-by-step explanation:

Notice that the triangles already have one pair of congruent sides and one pair of congruent angles.

Now, remember that the SAS congruence theorem refers to the congruence between two pairs of corresponding sides and one pair of corresponding angles. That means we just need another pair of congruent sides.

Therefore, the additional information we need is , because they are corresponding sides which make triangles ABC and ADE congruent.
