Question: In △ABC, AB = 3 and, AC = 4 cm and AD is the bisector of ∠A. Then, BD : DC is — Solution: BD/DC = AB/AC =34 So, BD : DC = 3 : 4. In did not understand how we proved the similarity and how we are taking the sides proportionality. Plz explain. Thank you.

In △ABC, AB = 3 and, AC = 4 cm and AD is the bisector of ∠A. Then, BD : DC is —

Solution:

BD/DC = AB/AC =34

So, BD : DC = 3 : 4.
