Well, you aren't going to get very many angles greater than 360 degrees!  :-)

In any event, folding the disk 3 times will yield 8 "pie slices" so to speak.

Each time he folds, the number of central angles is multiplied by 2. On the first fold there is 2, second fold 2 x 2 = 4, third fold 4 x 2 = 8.
