The system of hard squares and triangles of equal sides, for which the free volumeapproximation predicts entropic phase separation in the solid phase, is studied in the densefluid region, close to melting. The standard Monte Carlo simulations are inconclusiveconcerning the possibility of the phase separation in the dense fluid. By applying correlatedmotions of the particles, we present a direct evidence that, in contrast to the dense solidphase, the squares and triangles mix in the fluid phase.
