Parallelogram Theorem 6:Line segments joining the mid-points of the opposite sides of a quadrilateral bisect each other
In this video, we learn how to apply Congruency Rule to solve Problems on Qudrilaterals. Use parallel lines concept and triangle congruence theorems to prove/solve problems on properties of parallelograms.Understand the concept of Mid point theorem.
Reference book for the above video is
National Council of Educational Research and Training (NCERT) Book for Class 9 Subject: Maths
0:02 CBSE class 9 maths NCERT Solutions chapter 8 Quadrilaterals q6 Show that the line segments joining the mid-points of the opposite sides of a quadrilateral bisect each other.
00:59 Aim of solving problem
01:30 Analyse triangle to pull relevant imformation and apply converce of Mid point theorem.Converce of Mid point theorem states that the line drawn through the mid-point of one side of a triangle, parallel to another side bisects the third side
02:26 Use Mid point theorem
03:35 From property of Parallelogram : Opposite angels are equal & Opposite sides are equal.
