In `triangleABC`the bisector of `angleB` meets AC at D. A line PQ||AC meets AB,BC and BD at P, Q and R respectively.
show that `PRxxBQ = QRxxBP`.

In Delta ABC , the bisector of angle B meets AC at D. A line PQ||AC meets AB,BC and BD at P,Q and R respectively. Show that BPxxQR=BQxxPR .

In A B C , the bisector of /_B meets A C at D . A line PQ||AC meets A B , BC and BD at P ,Q and R respectively. Show that (i) PR*BQ=QR*BP (ii) AB*CQ=BC*AP

In DeltaABC, AB = AC and the bisectors of angleB and angleC meet AC and AB at point D and E respectively. Prove that BD = CE .

In DeltaABC, AB = AC and the bisectors of angleB and angleC meet AC and AB at point D and E respectively. Prove that BD = CE .

AD is a median of triangleABC . The bisectors of angleADB and angleADC meets AB and AC in E and F respectively prove that EF||BC.

In triangleABC , if the AD is a bisector of angleA show that AB>BD and AC>CD

In DeltaABC , AC > AB and bisector of angleA meets BC and D then angleADB is :

In DeltaABC , AC > AB . The bisector of angleA meets BC at D. Prove that angleADB is an acute angle.
