SECTION D e and Prove Midpoint theorem of triangle. te and Prove Central Angle Theorem of Circle.
The line segment joining the mid-points if two sides of a traingle is parallel to the third side.
E and F are mid-points of AB and AC respectively.
Also, CD parallel to BA.
Tr.AEF congruent to Tr.CDF (ASA Rule.)
So,
EF=DF AND BE=AE=DC
Therefore, BCDE is a parallelogram.
Thus gives EF is parallel to BC.
Also,
EF=1/2ED=1/2BC.
