Question

can any one solve this​

Answer 1

Step-by-step explanation:

Let Q be the point where EF intersects diag. DB,

In Δ ABD,

Q is the mid point <MID POINT THEOREM: line passing through one of the midpoints of one side intersecting the other is parallel to the third>

similarly, in Δ BDC,

∵QF ║ AB which is ║ DC

⇒ QF ║ DC

∴ F is the mid point of side BC <MID POINT THEOREM: line passing through one of the midpoints of one side intersecting the other is parallel to the third>

HENCE PROVED
