Coordinates and Shapes

Where is the point? Given three points on the coordinate plane, the video walks through the steps to find the location of the fourth point to create a given special quadrilateral. The narrator first determines the coordinates of the points on the graph. Using properties of the special quadrilateral, he then determines the location of the missing vertex.
