Abstract. In this paper we prove that if 1 2,P P are isogonal points in the triangle ABC, and if 1 1 1A B C and 2 2 2A B C are their corresponding pedal triangles such that the triangles ABC and 1 1 1A B C are homological (the lines 1 1 1, , AA BB CC are concurrent), then the triangles ABC and 2 2 2A B C are also homological. Introduction. In order for the paper to be self-contained, we recall below the main definitions and theorems needed in solving this theorem. Also, we introduce the notion of Orthohomological Triangles, which means two triangles tha
