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

To prove that a rhombus is a parallelogram, you must prove that it either satisfies the definition of a parallelogram or satisfies any of the theorems that prove that quadrilaterals are parallelograms. Here is a paragraph proof: A rhombus is a quadrilateral with four congruent sides, therefore opposite sides of a rhombus are congruent.Proving Quadrilaterals Given the four coordinates, draw a diagram of your quadrilateral.
