Answer:
Option D. ∠B ≅ ∠E
Explanation:
In ΔABC and ΔDEF,
Measure of side AB = Measure of side DE = 10 units
∠A ≅ ∠ D ≅ 45°
Now we have to prove ΔABC ≅ ΔDEF by the property of congruence ASA.
Since one angle and one side are equal.
So other angle based on sides AB and DE will be the adjacent angles ∠B and ∠E
Therefore, Option D. ∠B ≅ ∠E will be the answer.
