Answer: Two plane figures are congruent if and only if one can be obtained from the other by a ... The transformation would need to include a dilation, which is not a rigid motion. ... sequence of rigid motions must also produce a ... cannot not be mapped using only rigid motions, so they cannot be congruent.
Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent. ....................................................................................................................................
