ORTH. PROJECTIONS OF MORLEY TRIANGLE VERTICES -1

Let A'B'C' be the Morley 1st Triangle.

Denote

A'b, A'c = the orthogonal projections of A' on AB', AC', resp.

B'c, B'a = the orthogonal projections of B' on BC', BA', resp.

C'a, C'b = the orthogonal projections of C' on CA', CB', resp.

1. A'b,A'c, B'c, B'a, C'a, C'b are concyclic (??).

2. The Euler Lines of A'AbAc, B'B'cB'a, C'C'aC'b are concurrent (??).
