TSTST 2020 Problem 2

    Let ABCA B C be a scalene triangle with incenter II. The incircle of ABCA B C touches BC‾\overline{B C}, CA‾,AB‾\overline{C A}, \overline{A B} at points D,E,FD, E, F, respectively. Let PP be the foot of the altitude from DD to EF‾\overline{E F}, and let MM be the midpoint of BC‾\overline{B C}. The rays APA P and IPI P intersect the circumcircle of triangle ABCA B C again at points GG and QQ, respectively. Show that the incenter of triangle GQMG Q M coincides with DD.
