Re: [EMHL] AltiEulerian Triangles
- Dear Antreas,
Interesting question generates interesting result:
The rectangular circumhyperbola passing through A, B, C, H and P* has center at concurrent point Q.
Here H is orthocenter of ABC, P* is isogonal conjugate of P wrt ABC and P* is also orthocenter of triangle PaPbPc.

whose r. c/hyperbola the center is.
