Converse of Mid Point Theorem : The line drawn through the mid-point of one side of a triangle, parallel to another side, intersects the third side at its mid-point.
GIVEN in which D is the mid-point of AB and To Prove E is the mid-point of AC. Construction : Assume F to be mid point of AC. Join DF PROOF As we have assumed F to be the mid-point of AC. Now, in D is the mid-point of AB [Given] and F is the mid-point of AC. Therefore, by Mid Point Theorem, we have .....(i) But we are given that , ......(ii) From (i) and (ii) , we find that two intersecting lines DE and DF are both parallel to line BC. This is a contradiction to the parallel line axiom. So, our supposition is wrong. Hence, E is the mid-point of AC. |
Illustration:In the figure l,m and n are parallel lines intercepted by two transversal p and q such that l,m and n cut-off equal intercepts AB and BC on p. Show that l,m and n cut off equal intercepts DE and EF on q.
Solution: Join AF meetin BE at G In ACF B is the mid point of AC and BG || CF because it is given that m and n are parallel. By Converse of Mid Point Theorem G is the mid point of AF In AFD G is the mid point of AF and GE || AD because it is given that l and m are parallel. By Converse of Mid Point Theorem E is the mid point of DF Hence DE = EF |
E is the midpoint of median AD of ABC and BE is produced to meet AC at F. If AC = 30 cm, then find AF. | |||
