For being in the ratio 1:2:3:6, one of the angles of the quadrilateral has to be 180 degrees, which is not possible.
REASON:- Then the number of sides in the figure will be 3, not 4 as on 180 degrees it will become a straight angle.

Because,
x + 2x + 3x + 6x is not equal to 360
Hence quadrilateral cannot be formed
