Question

maths question no 24

Answer 1

We can prove this by congruency
Make a triangle ABC
Draw a median in the triangle say AB
So,
In triangle ABC
AB=AC (GIVEN)
AD=AD (COMMON)
BD=CD (BY CONSTRUCTION)
So by SSS congruence
Triangle ABD is congruent to triangle ACD
Therefore, angle B = angle C (by cpct)

Hence proved!

Hope it helps.
