If triangle ABC can be mapped onto triangle DEF through a sequence of rigid motions, which conclusion is not always true? 
1) Triangle ABC congruent to Triangle DEF.   - Always true.

2) Angle BAC congruent to angle FDE.         - Not always true.

3) line BC congruent to line DF.             - Not always true.

4) Angle CBA congruent to angle FED.         - Not always true.
