Given a triangle, we construct a one-parameter family of triads of coaxial circles orthogonal to circumcircle and mutually tangent to each other at a point on the circumcircle. This is a generalization of the classical Apollonian circles which intersect at the two isodynamic points.
Keywords: Apollonian circles, barycentric coordinates, circumconics.
