The best answer I can give based on the information you provided is to take a pizza, round or square or rectangular, and make two cuts from one side to the other perpendicular (at right angles) to each other.
For a round pie, find where the greatest diameter is and cut all the way across then do the same in the perpendicular direction. You'll end up with 4 wedges, each 1/4 the size (area) of the whole pie.
For a rectangular (including square) pie, measure the distance of each side from one corner to the other, find the midpoint and cut across the pie from one side to its opposite. Do the same in the perpendicular direction and you'll have 4 smaller rectangles, each 1/4 the size (area) of the whole pie.
