Slicing/Filling Image/Canvas With Other Images Diagonally

[gimpuser]

Hello. New Gimp user here, so hopefully posting in the right place. Using GIMP 2.10.14 on Mac, I would like to create a background image/wallpaper for a website similar to the attached--please see (also here is a link to the sample background image: adpartnersagency.  Edit: that is a bit too close to advertising, this the one with the three images - https://i.imgur.com/jKOLzeP.jpg - rich). So basically I am looking to:

1. Place three original images across one canvas, creating a single new image.
2. Have all three original images on the canvas / new image separated by two equidistant diagonal lines.

Any help as to the best way to do this would be much appreciated. Thank you!

All sorts of ways. Hopefully you will get some alternatives.

This is the way I prefer - using a layer mask. Part of this is skewing a selection using unified transform & ctrl - drag For a Mac the command key should replace ctrl.

Awesome! Thank you so much! That worked out well. One question. Not sure how much this matters, but I noticed your PPI was set to 96 when you created a new canvas/image. Mine was 72, but I used a much larger canvas size (3840 x 2160). Would that be the reason? Should I create a smaller canvas to have better resolution?
