5G-s-P3: 5G-Inner Miquel Points Center
Given a Pentagon P1P2P3P4P5. We denote the intersection of P1P3 and P2P5 by P12. Similarly P23, P34, P45 and P51 are defined.
The 5 Miquel points M12, M23, M34, M45, M51of resp. P1P12P2P4, P2P23P3P5, P3P34P4P1, P4P45P5P2 and P5P51P1P3 are concyclic.
See Ref-34, Seiichi Kirikami, QFG#760.
Properties:
• 5G-s-P3(P1.P2.P3.P4.P5) = 5G-s-P4(P1.P3.P5.P2.P4). See Ref-66, QPG-message #1398.
• 5G-s-P3(P1.P3.P5.P2.P4) = 5G-s-P4(P1.P2.P3.P4.P5).
