Answer 1

Answer:

a and? please tell so that I can help

Answer 2

Step-by-step explanation:

Join AC.

We get two triangles-

triangle ABC and triangle ADC.

Now in triangle ABC & ADC-

AD=AB (given)

DC=BC(given)

AC is common side.

so,

ABC is congruent to ADC.

therefore,

<DAC=<BAC by C.P.C.T.C.

therefore,

AD bisects <A.

Hence proved.
