please give me ans of this question​

Answer 1

Answer:

1. a. AB & AC

b. BD & DC

c. AD common side

2. They are equal triangles .

3. Corresponding angles.

Answer 2

Answer:

(i) AB = AC (given)

∠BAD = ∠CAD (given; AD is the bisector of ∠BAC)

AD = AD (common)

(ii) Yes.

AB = AC (given)

∠BAD = ∠CAD (given; AD is the bisector of ∠BAC)

AD = AD (common)

Hence, ΔADB ≅ ΔADC (by SAS congruence rule)

(iii)  Yes. As both ΔADB & ΔADC are congruent, So by C.P.C.T.  ∠B = ∠C.
