Explanation:

Step1: Recall congruence - preserving transformations

Congruence - preserving transformations (isometries) are rotation, reflection, and translation. These transformations do not change the size and shape of the figure.

Step2: Analyze dilation

Dilation is a transformation that changes the size of a figure. If the scale factor \(k
eq1\), the pre - image and the image are similar (same shape, different size). Since congruent figures must have the same size and shape, dilation does not preserve congruence.

Answer:

Dilation
