Finding Coordinates and Vertices

The video tutorial explains how to find the coordinates of a missing vertex in a rectangle given three vertices. It demonstrates plotting points on a Cartesian plane and provides a simple method to calculate the missing point using coordinate addition. An alternative method using rise and run is also discussed. The tutorial concludes with tips for efficiently solving similar geometry problems.
