#### Activity overview:

Mid Point Theorem Proof from Basic Proportionality Theorem | Converse of Basic Proportionality Theorem.

Mid Point Theorem
A line drawn through the mid-point of one side of a triangle parallel to another side bisects the third side

Basic Proportionality Theorem
If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.

Converse of Basic Proportionality Theorem
If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side.

00:03 Q7. Using Theorem 6.1, prove that a line drawn through the mid-point of one side of a triangle parallel to another side bisects the third side. (Recall that you have proved it in Class IX).
00:28 Use Basic proportionality theorem.
02:43 Q8. Using Theorem 6.2, prove that the line joining the mid-points of any two sides of a triangle is parallel to the third side. (Recall that you have done it in Class IX).
03:14 Converse of Basic proportionality theorem.
04:55 Q9. ABCD is a trapezium in which AB || DC and itsdiagonals intersect each other at the point O. Show that AO/BO = CO/DO.
05:54 Construction procedure tosolve the problem
07:14 Apply Basic proportionality theorem.
