ABC is a triangle in which /_B=2/_C*D is a point on BC such that AD bisects /_BAC and AB=CD. Prove that /_BAC=72^(@) .

In Delta ABC , DE || BC . If AD= 5 cm , BD = 7 cm and AC = 18 cm , find the length of AE.

Check whether AD is bisector of angle A of triangle ABC in each of the following . (i) AB = 4cm, AC = 6cm, BD = 1.6 cm , and CD = 2.4 cm (ii) AB = 6cm , AC =8cm , BD = 1.5 cm and CD = 3 cm

Check whether AD is bisector of angle A " of " Delta ABC 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.

D and E are respectively the points on the sides AB and AC of a triangle ABC such that AD = 2cm, BD = 3 cm, BC = 7.5 cm and DE |\ | BC. Then, length of DE (in cm) is (a) 2.5 (b) 3 (c) 5 (d) 6

D and E are respectively the points on the sides AB and AC of a triangle ABC such that AD = 2 cm , BD = 3 cm , BC = 7.5 cm and DE || BC. Then length of DE (in cm) is (a) 2.5 (b) 3 (c) 5 (d) 6
