Question

ABC is a triangle . PQ is a line segment intersecting AB in P and AC in Q such that PQ parallel to BC and divides triangle ABC into two equal parts in equal areas . Find BP/AB

Answer 1

when the any line in traingle which is intersect it two sides and parallel to the third side then the both sides are divided into two equal parts.

so, let AB =1 the BP =1/2

now BP/AB =1/2
