Equal Detour Point
The center of an outer Soddy Circle. It has Triangle Center Function
Given a point
not between 
and 
, a detour of length 
is made walking from
to via , the point is of equal detour if the three detours from one side to another via are equal. If 
has no Angle 
, then the point given by the above TrilinearCoordinates is the unique equal detour point. Otherwise, the Isoperimetric Point is also equal detour.
