Presenting Effective Argruments and Proofs

You may be wondering: "How do I solve a proof?" Well, that's a good question....
The first thing you need to know about proofs is that there are two columns. The first column is the "Steps" column. The second column is titled "Reasoning." In the first column you put how you solved or proved the proof, and the second column explains how your steps are possible according to theorems and postulates. There are different types of proofs, such as algebraic and geometric. The example with red dividers is an algebraic proof and the other example is of a geometric proof. This year in geometry we will focus on geometric proofs and building on these proofs. The picture above shows what a proof looks like. You solve a proof by using deductive reasoning, which is when you come up with effective arguments to present your options for the proofs. This is also known as deductive logic. There's a multitude of postulates and theorems that you can use in order to get a better understanding of what could possibly go under the "Reasoning" column.
