Answer 1

Answer:

Step-by-step explanation ∆ DBC is isoceles since base angles are equal . Therefore , DB is equal to DC. In ∆ABD and ∆ACD, Ad is common and DB = DC and AB = AC. Therefore, by SSS congruence they are congruent . By CPCT we can tell that angle BAD =DAC. This implies that AD bisects angle A
