Prove or disprove, that the points of intersection of the adjacent trisectors of the angles of any triangle are the vertices of an equilateral triangle. (
In other words, that for any yellow triangle, the green triangle will be equilateral, given that the thinner lines trisect their respective angles.)

In your second post, you have
(A+B+C=180)/3 = A/3 + B/3 + C/3 =120
This should be A/3 + B/3 + C/3 = 60.
