Answer:
A, B, C, D, E
Explanation:
AB ≅ AC and AD bisects ∠A
This is given information from the diagram and the statement.
∠BAD ≅ ∠CAD
This is from the definition of angle bisector.
AD ≅ AD
This is reflective property of congruence.
ΔABD ≅ ΔACD
From the previous three statements, side-angle-side congruence tells us the triangles are congruent.
∠B ≅ ∠C
Corresponding parts of congruent triangles are congruent.
