Problems with angles...

Alright, so I'm trying to make a graph with Photoshop, 'cept it's not a normal graph. I'll post a link to the image real quick-like... (The original image and working copy are much, MUCH larger. Yay for stock photos!) http://i20.photobucket.com/albums/b229/the_wotism/GIGANTOR-BUN-smaller.gif

The angles are measured and everything, the problem I have is that I can't seem to separate all four of the pieces in an equal distance or angle. Anyone have any advice on this?

(I know it isn't very clear to explain, which may be part of my problem to begin with. Maybe Photoshop wasn't built do do these things?)

Thanks in advance, dear Photoshoppers.

You must pull them out of the circle (explode the pieces).
Was I clear?
