Question

please tell me the answer​

Answer 1

Step-by-step explanation:

(i) AD = DC

Description:- As ABC is an isosceles triangle and AD bisects angle A in the middle. Therefore it proves that it also bisects lineBC at the middle forming a pointD

Hence, BD = DC

Soln:-

= BD + DC = BC

= 2(BD) = BC

= BD = BC/2

= BD = 1/2BC. {equation no. (i)}

That is BC = BD + DC

Thus, verified

(ii)- AD bisects BC

Soln:- According to equation no. I

BC = BD + DC

therefore, AD divides/bisects BC equally into two parts
