Answer 1

Answer:

2cm

As we know the midpoint theorem

"The line-segment joining the mid-points of any two sides of a triangle is parallel to the third side and is half of it."

Step-by-step explanation:

if BC = 4 CM

then BD=2cm(midpoint theory)

and ATQ,

BDEF forms a quadrilateral

and opposite sides of quadrilateral are equal

therefore EF=2cm
