Question

text  In the given triangle  end text fraction numerator L K over denominator K J end fraction equals fraction numerator L M over denominator M N end fraction text  then  end text

  1. LK=LM
  2. KM=JN
  3. KM ll JN
  4. KJ  ll MN

hintHint:

If a line is drawn parallel to any one side of a triangle so that it intersects the other two sides in two distinct points, then the other two sides of the triangle are divided in the same ratio.

The correct answer is: KM ll JN


    In the given triangle, we have LK/KJ = LM/MN, then we have KM is parallel to JN.
    Hence, the correct option is B.

    It is also called basic proportionality theorem.
