D is a point on the side BC of a ∆ ABC such that AD bisects ∠BAC. Then

In ∆ PQR, if ∠R > ∠Q, then

In Fig.7.3, PQ > PR and QS and RS are the bisectors of ∠Q and ∠R, respectively. Show that SQ > SR.

Q is a point on the side SR of a ∆ PSR such that PQ = PR. Prove that PS > PQ.

D is any point on side AC of a ∆ ABC with AB = AC. Show that CD < BD.

In Fig. 7.8, AD is the bisector of ∠BAC. Prove that AB > BD.
