Question

ABC is a isosceles triangle o is a mid point on the median ad. prove that AD bisects angle BAC of a triangle ABC​

Answer 1

Answer:

See ur answer!!!

Step-by-step explanation:

In quadrilateral ABCD we have

                  AC = AD

            and AB being the bisector of ∠A.

            Now, in ΔABC and ΔABD,

                  AC = AD

[Given]

                  AB = AB

[Common]

∠CAB = ∠DAB [∴ AB bisects ∠CAD]

            ∴ Using SAS criteria, we have

                  ΔABC ≌ ΔABD.

            ∴ Corresponding parts of congruent triangles (c.p.c.t) are equal.

            ∴ BC = BD.

Answer 2

Answer:

triangle o is a mid point on the median ad. ABC

equal & BAC prove that of a triangle ABC.
