Theorem tgextancgra 33074

Description: The exterior angle is NOT congruent to the remote interior angle -- the strictness tgextale 33071 cannot give, and what tgaas 33086's contradiction branch needs. The exterior angle is ⟨“𝐴𝐶𝐷”⟩, at the extension of 𝐵𝐶 beyond 𝐶. The tail of GeoCoq's l11_41_aux , run through acopyeu 29342 rather than conga_cop_or_out_ts : a congruent exterior angle would, by angle-construction uniqueness, put the midpoint-reflected point of tgmircgra 33066 on the ray 𝐶𝐷-- the two rays make congruent angles with the shared base ray 𝐶𝐴 and, by tgextahp 33073 and hpgid 29244, lie on the same open half-plane of line 𝐴𝐶-- which tgextamirnhl 33072 forbids. Both of acopyeu 29342's non-collinearity hypotheses are discharged, not assumed: source side by rotating the triangle's own ncol , target side by tgextancd 33068. (Contributed by JAG, 12-Aug-2026.)
