HYACINTHOS 214

  • Dear all,

    At the moment it seems that I only have time to do tiny problems. And
    probably this one is already known, but I was surprised by it:

    Let A'B'C' be a triangle inscribed in ABC (so A' lies on BC, etc.).
    Determine the radical center of the circles with diameters AA', BB' and
    CC' respectively.

    Kind regards,
    Floor van Lamoen.
