In the given figure, DE||AC and DF||AE Prove that 
Answer :
Given, DE || AC and DF || AE
Need to prove 
⇒ In 
ABC, DE || AC
⇒ now, we know line drawn parallel to one side of triangle, intersects the other two sides in distinct points, then it divides the other 2 side in same ratio.
⇒ 
………eq(1)
⇒ In 
AEB, DF || AE
⇒ 
………eq(2)
From (1) and (2)
⇒ 
Hence proved.
