Let n points in the plane be given whose coordinates we don't know. Assume, however, that for any triple of the points we know the angle.

Question: Can we decide whether the n points are realizable in the plane (i, i.e., can we determine whether there is an assignment of coordinates to the points s.t.such that the angular constraints are satisfied)?

Are angles between points enough to decide the realizability?
