What Is a Flow Proof in Geometry?

A flow proof is just one representational style for the logical steps that go into proving a theorem or other proposition; rather than progress downward in two columns, as traditional proofs do, flow proofs utilize boxes and linking arrows to show the structure of the argument. All of the theorems, properties, definitions and postulates that support each step appear next to the boxes.
