QA-P25: 1st QA-Quasi Centroid
QA-P25 is the Centroid of the triangle formed by the 3 QA-versions of QG-P4 (1st Quasi Centroid), constructed in the QA-Quadrigons of a Reference Quadrangle.
Coordinates:
1st CT-Coordinate:
(q + r) (2 p + q + r) (2 p (p + q + r) + 3 q r)
1st DT-Coordinate:
(q2 - r2)2 - p4 + 10 p2 (-p2 + q2 + r2)
Properties:
- QA-P5.QA-P25 : QA-P25.QA-P1 : QA-P1.QA-P10 = 8 : 1 : 3.
- QA-P25 is the Reflection of QA-P26 in QA-P1.
