Q3 of 42 Page 202

In the given figure, DE||AC and DF||AE Prove that

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.
