1.	△ABC is isosceles with AB = AC. Line segment AD bisects ∠A and meets the base BC in D.(i) Is △ADB≅△ADC?(ii) State the three pairs of matching parts used to answer (i).(iii) Is it true to say that BD = DC?
Answer» $△ A B C$ is isosceles with AB = AC. Line segment AD bisects $∠ A$ and meets the base BC in D. (i) Is $△ A D B ≅ △ A D C ?$ (ii) State the three pairs of matching parts used to answer (i). (iii) Is it true to say that BD = DC?
