Summary Symmetry, circumcircles, and angles of intercepted chords are some of the ingredients, as mathematicians give dissection proofs of the pizza theorem to show that they can get their fair share, even when the original pizza cuts are off-center. And with just a slight variation in the recipe, we also get a dissection proof of the calzone theorem.
