WebMar 26, 2016 · If you cut a pizza into four big slices and then cut each of those slices in half, you get eight pieces, each of which makes a 45° angle. If you cut the original pizza into 12 slices, each slice makes a 30° angle. So 1/12 of a pizza is 30°, 1/8 is 45°, 1/4 is 90°, and so on. The bigger the fraction of the pizza, the bigger the angle.
