Example 3
If in a triangle PQR a line parallel to QR cuts
PQ and PR at x and y respectively, such that
l (seg.PX) = 12 ,
l (seg.XQ) = 8 and l
(seg.PY) = 9 find (seg.YR).
Solution:
Example 4
In D
ABC, seg.BP is the bisecter of Ð
B. If
l
(seg.AB) = 3, l (seg.BC)
= 5 and
l
(seg.AP) = 1.5, find l
(seg.PC).
