Answer:
C, D, and E are corrects.
Step-by-step explanation:
Two plane figures are congruent if and only if one can be obtained from the other by a sequence of rigid motions. The rigid transformations are reflection, rotation, and translation. The image from these transformations will not change its size or shape.
A dilation is a nonrigid transformation that can produce enlarged or reduced images from a given pre-image.
Therefore only C, D, and E are corrects.
A. a dilation, then a translation
B. a reflection, then a dilation
C. a reflection, then a rotation
D. a rotation, then a translation
E. a translation, then a reflection
