Homework Help: A Problem On Similarity

  1. Mar 5, 2010 #1
    Hi ,there

    ABC is a triangle , D is the midpoint of AB , from D draw a st. line to intersect AC at H and BC at O.
    Prove that :

    AH : HC = BO: OC

    We need to solve this problem using the similarity theorem "If a line is drawn parallel to one side of a triangle and intersects the other two sides , then it divides them into segments whose lengths are proportional ".

    Thanks in advance
