#### Storyboard Text

• I have geometry homework that's due tomorrow but I don't understand geometry two-column proofs!
• Geometry
• Geometry Help now!﻿
• Hi, I'm Bella, and today, I am going to be teaching you about geometry two-column proofs. Let's get started!
• A paragraph proof is a type of proof that explains the rationale for each step using complete sentences in paragraph form. Oftentimes, before creating a paragraph proof, most people put it into two-column proofs first to make it easier to organize.
• There are two many different types of proofs used in geometry but the two most common used proofs, are paragraph proofs and two-column proofs. Two- column proofs is a table with two columns; the first column is the mathematical statement, and the second column is the justification.
• Now that you know the definition of two-column proofs let's get to an example,now shall we. Lets begin with something easy, algebraic proofs.
