2-7 Flow Proofs

0Thus far, we have been doing two-column deductive proofs to prove Geometry theorems.

0 Two other styles of proof that are sometimes used are the flowchart proof and the paragraph proof.

0 In this class you will be allowed to complete a proof in either Two-Column or Flowchart. But you must know how to complete both types.

Flowchart Proofs

0The steps in a flowchart proof move either from left to right or from top to bottom0Arrows connect each box, and the

justification for each step is written below the box.

We will prove this theorem in both flowchart and two-

column form
