I tried using apollonius theorem to find the length of BF and used similar triangles DBF and DBC to find the length of DF. But i am not getting 2 units. Please help me solve.Is there anything wrong with the method i choose to work. Reply

Sir it shud be two lines to the side of length k..

Edited Girish, thanks!

can bring out sums : on the application of appolonius theorem will be useful

oh, my mistake, i got it. it should be 2 only
