What is this woodworking technique called?

I was watching a “I like to make stuff” video on the YouTube where he was making a shadow box. For the outside of the box, he took a board (1x4 ish), cut 3 90 degree notches in to allow the wood to fold or bend into a square.
what is this called?

If the notches weren't cut all the way through, that's know as kerfing. I've never seen it done for a 90 degree bend, though. It's usually a whole bunch of saw cuts to allow a thick board to bend into a curve without steaming it.

It is called a Miter Fold Dado.

Back in the day we designed this into a fixture system and produced 73.8 miles of Miter Fold Millwork for 1 project. Worked great.

The Millwork Column on this Fixture was Miter Folded. The substrate was MDF with a Laminate and Chem Metal glued on prior to machining. Made for nice ridged column. Eventually the Posters were swapped out for Digital Media...Flat Screens, some Touch Screens to interface with the clients.

Is this what you are talking about?

I don't know if that's the exact tool her used, but that is slicker than whale snot! It cost more than my whole table saw. I won't be a buyer, but if I wanted to get serious about making some furniture, that would be on my short list.

you can cut with router rabbet or straight bits, not as efficient and might require multiple pass and some sort of jig to make it cut straight. plenty of video on that as well...
maybe post the said video you were watching, pretty sure the wood working guys here will be able to easily identify that for you.

Joining Wood Together With Half Lap Joints

Half lap joints are easy to make with a table saw or a radial arm saw. Simply remove half of the material from two boards and fit them together.

Just run your table saw a 45* with a dado blade

Make the pass just shy of the laminate, heat, fold, glue, clamp.

requires materials that have a laminate/veneer to accomplish, otherwise you are just gluing and nailing again
