triangle ABC ,D& E are the mid-points of AB &AC respectively through E , a straight line is drawn parallel to AB to meet BC at F. Prove BDEF is a parallelogram.
if AB is equal to 16 cm ,AC is equal to 12 cm , BC is equal to 18 cm .find the perimeter of BDEF.

I am sending photo of answer
the scenes D and e are the midpoints of a b and ac respectively this implies that b is equals to half of b c and b is parallel to BC by mid point theorem it is given that EF is parallel to a b this implies that DP is also parallel to EF SDB is the part of a b and prove that b f e d is a parallelogram as its opposite sides are parallel
