[ABC" is a triangle.Lines are drawn through the vertices "A,B" and "C" parallel to "],[bar(BC),bar(CA)" and "bar(AB)" respectively,forming "Delta PQR" .Show that "BC=1/2PR" ."]

Given Delta ABC, lines are drawn through A,B and C parallel respectively to thesides BC,CA and AB, forming Delta PQR( Fig.13.27 ).Show that BC=(1)/(2)QR

Given triangle ABC, lines are drawn through A, B and C parallel respectively to the sides BC, CA and AB forming PQ . Show that BC= 1/2 QR
