How do we prove that a triangle with sides $(one, x, y)$, where $x$ is any constructible length from one to three at the elliptic curve
$$y^2 = x^3 -x^2 -x +1$$then the triangle possess at least one trisectible angle?
I would like to add this note: *if $x$ is a constructible length or (any real number) from zero to one), then you would kindly notice that (3*Alpha - Beta = PI), where (Alpha & Beta) are two angles in the triangle $(one, x, y)$, which implies a trisectible angle*
