If a straight line meets the sides BC, CA, and AB of a triangle ABC in the points D, E, and F respectively
then
(AE/EC)* (CD/DB)* (BF/FA) = 1.

Prove the above theorem.

BTW the converse is also true.

Some consider me good,
and some consider me bad.

Some gather in my house,
because I am a part of a fad.

Sometimes I am dark.
and sometimes I am light.

I could be the savior at sunrise,
and sometimes the savior of night.

What am I?
