Q2 of 56 Page 135

In figure AD is the bisector of ∠A. If AB = 6 cm, BD = 8 cm, DC = 6 cm, then the value of AC will be:

Given,


AB = 6 cm, BD = 8 cm, DC = 6 cm


In ΔABC, AD is the internal angle bisector of angle A.


By internal angle bisector theorem, the internal angle bisector divides the opposite side in the ratio of other two sides.



Putting given values,
