Q. 7 E5.0( 4 Votes )

The bisector of P in ΔPQR intersects in D. If QD: RD = 4 : 7 and PR = 14, then PQ = ………..
A. 8

B. 4

C. 12

D. 16

Answer :

We have



Given: PD is the bisector of P.


QD:RD = 4:7


PR = 14


To find: PQ = ?


In ∆PQR, the bisector of P intersects the line QR at D. By property of triangles,





PQ = 2 × 4


PQ = 8


Thus, option (a) is correct.
