[A,B,C,D" are concyclic."AC" bisects "BD.AB=9cm,],[BC=8cm,CD=6cm," then "AD" is "],[[" (1) "7cm," (2) "10cm],[" (3) "12cm," (4) "15cm]]

A,B,C and D are concylic, AC bisects BD. If AB =9 cm, BC=8 cm, and CD=6 cm, then find the measure of AD.

IN DeltaABC AD bisects angleA . AB=6cm, BD=8cm and DC=6cm then AC=………..cm.

In the figure, if DF||BC, AD = 3cm, BD = 4cm and BC = 14cm, then DE equals (a) 7cm (b) 6cm (c) 4cm (d) 3cm

Construct triangle ABC with sides AB=5cm, BC=9cm, and AC=6cm.

If ABC is a triangle and AD bisects, AB=4 cm, BD=6 cm, DC=8 cm then the value of AC=____.

In traingle ABC , AD bisects angle A , AB = 5 cm, BD = 8 cm and DC = 6 cm then AC = ……….cm.

In the given figure, if AB = 12cm. BC = 8cm and AC = 10 cm, then AD = ………cm

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

In the adjacent figure,if AB=12cm,quad BC=8cm and AC=10cm then AD=(FIGURE)(a)5cm(b)4cm(c)6cm(d)7cm

In Fig.4.60,AD bisects /_A,quad AB=12cm,quad AC=20cm and BD=5cm, determine CD.( FIGURE )
