Dilation is changing the size of a shape. Remember, similarity is same shape, DIFFERENT size!
Translation is sliding a figure around. Does this change the figure? No!
Rotation is spinning the figure around. The figure is still the same. Remember, congruence is just a specific case of similarity.
Reflection is flipping the figure over. This also does not change the shape or size of the figure.
