This special point is a triangle center and it is designated as the center X(174) in Clark Kimberling's Encyclopedia of Triangle Centers. Peter Yff initiated the study of this triangle center in 1987. ==Isoscelizer== An isoscelizer of an angle ''A'' in a triangle ''ABC'' is a line through points ''P''1 and ''Q''1, where ''P''1 lies on ''AB'' and ''Q''1 on ''AC'', such that the triangle ''AP''1''Q''1 is an isosceles triangle. An isoscelizer of angle ''A'' is a line perpendicular to the bisector of angle ''A''. Isoscelizers were invented by Peter Yff in 1963. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yff center of congruence」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
