Jerome was curious if \triangle ABCâ–³ABCtriangle, A, B, C was congruent to \triangle FEDâ–³FEDtriangle, F, E, D, so he tried to map one triangle onto the other using transformations: Jerome concluded: "It's not possible to map \triangle ABCâ–³ABCtriangle, A, B, C onto \triangle FEDâ–³FEDtriangle, F, E, D using a sequence of rigid transformations, so the triangles are not congruent." What error did Jerome make in his conclusion?\
