Question

In the adjoining figure, AB=AC.......​

Answer 1

Step-by-step explanation:

(1) AB = AC(GIVEN)

BD = DC(AS D IS THE MIDPOINT OF BC)

AD = DA(COMMON)

(2)Yes, ABD&ADC ARE CONGRUENT

Because of the following conditions above, it follows SSS axiom

And thus TriangleABD is congruent to TriangleADC.

(3)Triangle ABC is an isoceles triangle as AB = AC

and BC is the base

And angle B & angle C are EQUAL

So, angle B = angle C
