「Generalized fish bases defined on ex-ellipses of a triangle:」 study in math
[Some further variations of the fish base: these contain the cases appeared in the preceding article: Generalized fish bases defined on excircles of a triangle as special ones.]
For an arbitrary triangle, there exist (many) 'ex-ellipses': each of which contacts an edge of the triangle and two others at these extended parts. The following example shows isogonal conjugate relations with respect to a triangle and one of those ex-ellipses [(Apollonius)]:
Applying this fact to a given triangle at each of its vertices, then the following diagram/graphic image will be realized:
