[math-fun] square into acute, isosceles ▲s
Yesterday, without telling him http://www.mathpuzzle.com/21oct02.html, I challenged Nico Brown, http://mathcircle.berkeley.edu/images/nico-vincent-bmmt.JPG (left, here winning the Berkeley Mini-Math Tournament) to find such a dissection. I think there were only three known. He just found the fourth: https://mail.google.com/mail/?ui=2&ik=97b2a014c7&view=att&th=149301580b6c08d... --rwg

As I asked James: When will math-fun emerge from the email stone age? On Mon, Oct 20, 2014 at 7:18 PM, Bill Gosper <billgosper@gmail.com> wrote:

Still awaiting Nico's answer to the algebraic degree(s) of the coordinates. Better yet, their equations.
