How to tie the edges of an image?

Question

Adobe Photoshop

Became interesting. Is there a feature in Photoshop that allows you to snap the edges of an image to each other?

For example, I want only half of, say, a square to be shown on top, but this picture will be a pattern and I need that what goes beyond the edge of the image is displayed symmetrically from below.

So that when the pictures are superimposed under each other, this square seems to merge together.

I did this manipulation with my hands, aligning to the grid, but I wondered if it could be done easier.
