QA-P31: Complement of QA-P16 wrt the Diagonal Triangle

 
QA-P31 is the complement of QA-P16 (QA-Harmonic Center) wrt the QA-Diagonal Triangle.
 
QA-P31-Complement of QA-P16 wrt DT-01
Coordinates:                       
1st CT-Coordinate:
            p (q + r) (2 p + q + r) (p2 + p q + 2 q2 + p r + q r + 2 r2)
 
1st DT-Coordinate:
            q2 + r2
 
 
Properties:
  • QA-P31 lies on these QA-lines:
        QA-P10.QA-P16        (-1 : 3 => QA-P31 = Complement QA-P16 wrt QA-DT)
        QA-P20.QA-P21        ( 1 : 1 => QA-P31 = Midpoint QA-P20.QA-P21)
