Question

1. Prove that the line segment joining the mid points of two sides of a triangle is parallel to
third side​

Answer 1

Answer:

The line segment joining the mid-points of two sides of a triangle is parallel to the third side. You can prove this theorem using the following clue: Observe the figure in which E and F are mid-points of AB and AC respectively and CD || BA. So, EF = DF and BE = AE = DC.
