If the diagonals of a quadrilateral are.. (part 3)

Last Friday I posted two GeoGebra files dealing with quadrilateral displays with congruent diagonals, and with diagonals that bisect each other.
In the attempt to make these one step closer to teacher-friendliness, I have combined them into one fairly self-explanatory file.

This should be added to in the near future.

The actual file can be found at http://tube.geogebra.org/m/1844613

Have fun.
