2. AB = AD by angle bisector theorem.

3rd im not sure

Answer 2

(i)..  a) Line AC is the common base for triangle DAC and BAC.

b) Both the angles in angle A are equal.

c) Both the angles in angle C are equal.

(ii)...  Yes BAC is congruent to DAC because all the angles are equal and Line AC is the common base.

(iii)... Yes by C.P.C.T.   (congruent part of a congruent triangle.)

(iiii)... yes by C.P.C.T.  (congruent part of a congruent triangle.)

May the answer help you.
