3 point circle determination_Constraints and a solution example

Caused a disadvantage condition  at some circle determinations of Three point technic is knowing.So,shortly,distribution as homogen of this three point is establishing to most sense solutions...But,some conditions are among extraordinary examples !!!For example,a patern distribution was distribute into  apprx a quarter environment...Where,I tested to usefulness of three point technic.And,I considered to condition of different combinations for four different event location into a quarter hinterland;

Thus,conclusion quite good...Also,circle route is supplementary as geomorphologic...I suggest a image thrusting software for other locations(as lost)
