Proving or Disproving Rectangles in the Coordinate Plane

The video tutorial explains how to determine if four points in a coordinate plane form a rectangle. It begins with a review of quadrilateral classification and then details the process of proving a shape is a parallelogram. The tutorial outlines five methods for this proof, focusing on the bisecting diagonals method. Once a parallelogram is established, the video demonstrates how to prove it is a rectangle by showing one right angle, using slopes to confirm perpendicularity. An example with specific points is provided to illustrate these concepts.
