Answer 1

Answer:

In ∆ABC and ∆ABD we have ,

AC = AD. ( Given)

AB = AB. .. ( Common)

since, AB bisects /_A , therefore,

/_CAB = /_DAB

hence , ∆ABC =^~(congruent) ∆ABD by SAS

Answer 2

Answer:

given- AC= AD

AB bisect A

To proove -ABC congruent to ABD

proof- AC=AD. (given)

AB=AB. (common)

A=A. (angle bisect into two

equal parts)

Therefore - ABCis congruent to triangle ABD. ( SAS)
