“…In the same way, we can observe what will be the locus of a certain line, or other object associated to triangles in a triangle family. Some results in this area, especially for the Euclidean plane can be found in [1,2,4,9,10,12], while [5,6,7] deal with the situation in the isotropic plane. This paper contains a family of triangles whose basic elements are dual to the family of triangles in [4] but the resulting locus curves are different.…”
