Answer:Given that ABC FED are congruent by the SSS Congruence Theorem, the rigid transformations that maps ABC onto FED are: B reflection, then translation.
Step-by-step explanation:Reflection is a from of transformation whereby a figure is flipped over a line of reflection, making both figures exactly the same shape and size after the transformation.
Translation is also another form of transformation whereby all the points of a figure are shifted at exactly the same distance and in the same direction without being resized, reflected nor rotated.
