please prove the mid point theorem
Hi!
Mid point theorem states that " the line segment joining the mid-points of any two sides of a triangle is parallel to the third side and equal to half of it".
⇒ ED | | BC (Opposite sides of parallelogram are parallel)
⇒ EF | | BC
EF = DF (Proved)
⇒ EF + DF = ED = BC (Opposite sides of the parallelogram are equal)
⇒ EF + EF = BC
⇒ 2 EF = BC
Cheers!
