2-7 Flow Proofs

2
**Thus far, we have been doing two-column deductive proofs to prove Geometry theorems.**

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

3
Flowchart Proofs The steps in a flowchart proof move either from left to right or from top to bottom Arrows connect each box, and the justification for each step is written below the box.

4
**We will prove this theorem in both flowchart and two-column form**

9
**Two Important Theorems**

10
**Write a two column or flow proof to prove the following:**
