Answer 2

Answer:

IN TRIANGLE ABD AND ADC

AB = AC (GIVEN)

AD = AD (COMMON SIDE)

BD = BC ( D IS THE MIDPOINT OF BC )

BY SSS AXIOM OF CONGRUENCY  ABD=~triangle ACD

ii) BY CONVERSE OF ANGLE BISECTOR THEOREM WHICH SAYS THAT " if a point D on the side BC of triangle ABC divides BC in the same ratio as the sides AB and AC, then AD is the angle bisector of angle ∠ A"
