'ABCD is a quadrilateral and X is a given Point in AD. Find a point Y in AB such that the area of triangle AXY is equal to that of ABCD'
Since it is a quadrilateral, I haven't reached anywhere using Congruency or similarity. For the same reason, I also have difficulty applying Melanus's theoem or Ceva's theorem.
Considering the question is among the first 10 questions of the exercise, it shouldn't be that complicated and thus I would be grateful if someone could point out what I am missing.
