Oblong: longer than wide, or wider than long (i.e., a rectangle that is not a square). [5] Kite: two pairs of adjacent sides are of equal length. Coordinate Proofs. In a coordinate proof, you are proving geometric statements using algebra and the coordinate plane.

If a quadrilateral is a parallelogram, then… Much of the information above was studied in the previous section.California State University, Northridge 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 The structure of a two-column proof must follow four basic precepts: Two-column Proof Structure. The first or left column has only mathematical statements, like "quadrilateral PINK is a parallelogram" or " side PI = side NK ." The second or right column has only reasons supporting the validity of those mathematical statements, like "Given," …The Structure of a Proof. Geometric proofs can be written in one of two ways: two columns, or a paragraph. A paragraph proof is only a two-column proof written in sentences. However, since it is easier to leave steps out when writing a paragraph proof, we'll learn the two-column method. A two-column geometric proof consists of a list of ...
