If you get stuck, work backward. Jump to the end of the proof and start making guesses about the reasons for that conclusion. You can almost always figure out the way by using the if-then logic to reach the previous statement (and so on). /em>. This proof that Sal demonstrates is called two-column proof. He is not writing all the steps since he has already given us the steps by word. However, the two-column proof is the basis of proof in geometry, and it is what you use to explain your actions in a problem (as Sal did two videos ago). The Postulates
