Make a perfect sector segment vector/PSD

Design details: I am making a mobile game where the pieces I need making can rotate around the circle. Therefore I need the images to be perfect in size and shape. Please look at the attached images and imagine the background circle to be a template for a jigsaw. Then each "segment" or "sector" will fit on top of it and make the shape perfectly. I will need 4 images which will make 1 sector which when duplicated will make the circle perfect. It is important there are no lines or gaps when put together. Colour in white please. File to be delivered in PSD format ( I may accept other formats) But I do need this today.
Ideas for the visual style: Please see photos
Things to avoid: No gaps or lines when placed together.
Preferred colors: White
Extra notes: I have only attached 3 of the 4 pieces to this job sheet as PPH only allow 4 images in total. but you can grasp the idea.
