Question

In fig., 4.60, check whether AD is the bisector of ∠A of ΔABC in each of the following:

(i) AB = 5 cm, AC = 10 cm, BD = 1.5 cm and CD = 3.5 cm
(ii) AB = 4 cm, AC = 6 cm, BD = 1.6 cm and CD = 2.4 cm
(iii) AB = 8 cm, AC = 244 cm, BD = 6 cm and BC = 24 cm
(iv) AB = 6 cm, AC = 8 cm, BD = 1.5 cm and CD= 2 cm.
(v) AB = 5 cm, AC = 12 cm, BD = 2.5 cm and BC = 9 cm

Answer 1

⇒ AD is not the bisector of ∠A.
