There is a pivot in the center. The pivot is attached to the frame that rotates when you angle it. It gets about 15 degrees of pivot in each direction so it will follow contours well. It's the stock small light truck (probably actually for a jeep) setup more or less. I made a bracket so I could drop the bracket on the quick hitch (the shiny piece I have since painted). Then removed the winch & just ran the chain to the top link of my quick hitch.
If I find another truck plow with hydraulic angle for cheap, I'll probably build a new one & try to sell this one for $500-700 (Cost me under $250 to make including the SSQA QH adapter scrounging garage sales). If I do end up building another one, I'll re-engineer it so the plow is much closer to the tractor. This one doesn't push me to the side bad at all, but I really can't make a tight turn with much load on the blade.
Here you can see it flopped to one side.

Here you can kind of see how it pivots on the nub used to adjust angle & the pivot point in front (loose bolt hole with a rubber washer underneath) at maximum tilt the plow frame will hit the plow subframe. The right side frames are touching in the picture, so it's articulated as far as it will go to the right, but will articulate much further to the left given the angle I have on the blade at the moment.
