superimposable
Can match exactly
Superimposable describes things that can be placed over one another so they match exactly, point for point.
The term appears most often in chemistry, where molecules that are superimposable on their mirror images are called achiral: The two structures are superimposable, so they're the same compound.
Outside science, the word describes any images or patterns that align perfectly when overlaid.
