Answer:
Explanation:
Consider triangles ABE and ACD:
- ∠BAC ≅ ∠CAB, common angle, congruent to itself
- ∠ABE ≅ ∠ACD, same arc DE intercepted
- AB = AC, given
According to above congruence statements, we can conclude:
- ΔABE ≅ ΔACD as per ASA postulate, since two angles and the included side are congruent
Since the triangles are congruent, we have:
- BE = CD as corresponding sides of congruent triangles
