What else would need to be congruent to show that ABC DEF by AAS?

Answer:
A. ∠A ≅ ∠D
Explanation:
Given:
• Angle: ,Angle F is congruent to Angle C
,• Side:, AB is congruent to DE.
For the two triangles to be congruent by AAS, we have:
• Angle: ,Angle F is congruent to Angle C
,• Angle: ,Angle A is congruent to Angle D
,• Side:, AB is congruent to DE.
Thus, the required condition for similarity is:
[tex]\angle A\cong\angle D[/tex]
