How to determine if a set of points makes up a rectangle using the distance formula

The video tutorial guides students through determining if a set of coordinate points forms a rectangle. It begins with a discussion on the characteristics that differentiate rectangles from parallelograms, emphasizing the congruence of diagonals. Students are instructed to plot points and assess the shape visually. The tutorial reviews the method for proving a shape is a parallelogram and then applies the distance formula to verify the diagonals' congruence, ultimately proving the shape is a rectangle.
