//Read till last// Prove that a line drawn throught the midpoint of one side of triangle parallel to another side besects the third side. Why we have to prove E as midpoint ?​

Answer 1

Prove that a line drawn through the mid-point of one side of a triangle parallel to another side bisects the third side (Using basic proportionality theorem). ... => E is the mid point of AC. Hence, it is proved that a line through the midpoint of one side of a triangle parallel to another side bisects the third side.
