Dear Nik,... [PY]: I wonder if the similarity ratio ZBaCa/ABC has a simple expression. [ND]: > The similarity ratio is > k = S/(aasin(2A) + bbsin(2B) + ccsin(2C)) > = 1/(3 - ss) >= 1/3 where s = OH/R > > Other properties of X184 are > X184 = X63 of the orthic triangle > X184 = X226 of the tangential triangle > and X184 is the homothety center of the orthic triangle > and the medial triangle of the tangential triangle. Thank you very much. Best regards Sincerely Paul Yiu
