Question

prove that the line joining the middle points of two sides of a triangle is parallel to the third side and is of half it's length​

Answer 1

Answer:

We conclude that the line joining the mid-point of two sides of a triangle is equal to half the length of the third side. The converse of this theorem states: If a line is drawn through the mid-point of a side of a triangle parallel to the second side, it will bisect the third side.
