Question

The incircle of an isoceles triangle ABC, in which AB = AC the sides BC, CA and AB at D, E and F respectively, Priove that BD=DC

Open in App

Solution

Since ABC is an isosceles triangle, the in centre would pass through the altitude (Eulen Line)
Thus, BD=DC
(Altitude & median are same in an isosceles triangle)
