please solve it fast it is very urgent

Answer 1

Consider an isosceles triangle ABC having AD as the median and AB = AC.

Given AD is the median.

⇒ BD = DC

In Δ ABD and Δ ADC, we have

AB = AC

BD = DC

and AD = AD

Therefore, Δ ABD Δ ADC  [SSS property]

⇒ ∠1 = ∠2  [cpct] 

Hence, the median from the vertex of an isosceles triangle is the bisector of the vertical angle.
