The transformations that always produce congruent figures are TRANSLATIONS, REFLECTIONS, and ROTATIONS. These transformations are isometric, thus, the figures produced are always congruent to the original figures.

The transformation that sometimes produce congruent figures is dilation. It can be enlargement or contraction. 

rule: (x,y) → (x+4,y+8)
