I like the idea of not having posts that impede moving around the garage.
-Top ledger -I attached the two perpendicular end pieces before I anchored it to the wall.
-I then added the bottom ledger
-For the angle, notched the bottom and followed the angle it created when it meet the two perpendicular sides
-I screwed the angle piece to the side, then cut them off to mirror the sides.
My cut off had enough length and proper angle to work for the second angle side.
