Title: Two Mappings of a Tetrad of Points and the Transformations of Noticeable Points Generated by Them Keywords: Noticeable Points, Tetrad of Points, Transformations of Noti Abstract: We study a set of transformations of remarkable points of a triangle. It is generated by a mapping of four points in the plane of a given ΔABC on the set of the triangles in that plane. The image of any tetrad of points by this mapping is a triangle perspective to ΔABC. We also consider the transformation of the four points onto a corresponding perspector. It generates various transformations of notable points, most of which are compositions of known mappings. References Issue
