Final answer:
The translation rule is AC' = A, C' = C, D' = D, and E' = E. The scale factor of the dilation is 1.
Step-by-step explanation:
The translation rule is found by subtracting the coordinates of the original figure from the coordinates of the transformed figure. In this case, the translation rule is AC' = A, C' = C, D' = D, and E' = E.
The scale factor of the dilation can be found by comparing the lengths of corresponding sides of the original figure and the transformed figure. In this case, since AC is congruent to AC', the scale factor is 1. Similarly, since DE is congruent to D'E', the scale factor is also 1.
