Problem
The magnitudes of the sides of triangle 
are 
, 
, and 
, as shown, with 
. Through interior point 
and the vertices 
, 
, 
, lines are drawn meeting the opposite sides in 
, 
, 
, respectively. Let 
. Then, for all positions of point , 
is less than:
![[asy] import math; pair A = (0,0), B = (1,3), C = (5,0), P = (1.5,1); pair X = extension(B,C,A,P), Y = extension(A,C,B,P), Z = extension(A,B,C,P); draw(A--B--C--cycle); draw(A--X); draw(B--Y); draw(C--Z); dot(P); dot(A); dot(B); dot(C); label("$A$",A,dir(210)); label("$B$",B,dir(90)); label("$C$",C,dir(-30)); label("$A'$",X,dir(-100)); label("$B'$",Y,dir(65)); label("$C'$",Z,dir(20)); label("$P$",P,dir(70)); label("$a$",X,dir(80)); label("$b$",Y,dir(-90)); label("$c$",Z,dir(110)); [/asy]](http://latex.artofproblemsolving.com/b/8/1/b8175dd073e666965c2dd3700b5b55a1823d0505.png)
