| Description: Two DISTINCT points 𝐹 and 𝐻 on one half-line from 𝐸, subtending congruent angles at a point 𝐷 off the line, are contradictory. ishlg 29068 unfolds the half-line to "one of them is strictly between 𝐸 and the other" -- both sub-branches are proved, each by tgaasexc 33081 on its own triangle, and they are not permutations of one another: the second needs the non-collinearity transported to line 𝐸𝐻 by cgrancol 29337.
