Q11 of 186 Page 263

In a ΔABC it is given that AB = 6 cm, AC = 8 cm and AD is the bisector of ∠A. Then, BD : DC = ?

By internal angle bisector theorem, the bisector of vertical angle of a triangle divides the base in the ratio of the other two sides.


Hence in ΔABC, we have



Here AB = 6 cm, AC = 8 cm


So
