This Controller uses a half-circle to express the 180 degree triangle angle sum. The base of the half-circle gives the direction and length of the resulting triangle base.

If these two points move freely on the half-circle, they specify an arbitrary triangle. Presume that the half-circle has a 0-1 parameter domain.     ... more on Design Patterns CA
