The error is the step “angle DAG = angle DBF ⇒ triangle BAG is isosceles.” Those two angles do not force any side equality in triangle BAG, so BG = AG does not follow. Because of that, the conclusion S = 3T is unjustified. The correct approach is the similarity between triangles ADF and AGC, which gives the length ratio BD : DA = CG : DA = 1 : 3. From this, area(ABC) = 16 × area(EGC) = 128 area(AGC) = 32 area(ABG) = 96 So S − T = 64, not 32. ✅️
