It is also known as Thales Theorem. It states that if a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points , then the other two sides are divided in the same ratio. Posted by Hayat Gandhi (student) on 22/8/09

the father of bpt izz thales so it izz know as thales theorem also :if a line izz drawn parallel 2 one side of a triangle 2 interscet the other 2 sides in distinct point then the other 2 sides r divided in the same ratio.if u wanna no converse of bpt reply me.
