Answer:
Option is D.
The congruence theorem that can be used to prove △BAE ≅ △CAD is HL (Hypotenuse and leg of a right triangle.)
Explanation:
From the Figure:
Consider △BAE ≅ △CAD
∴


Therefore, by HL i.e, (Hypotenuse and leg of a right triangle) which implies that two right angle triangle are congruent if their hypotenuse and one corresponding leg of the triangle are equal.
Hence,
by HL congruence theorem.
