    Thales Theorem in a Triangle

    • If a line parallel to one side of a triangle is drawn intersecting the other two sides, then it divides the two sides proportionally.
    • In the given triangle ABC, MN is parallel to BC, intersecting sides AB and AC at points M and N respectively
    • This implies that AM/MB = AN/NC
    • Further, AM/AB = AN/AC = MN/BC.
