Exploring Polygons and Their Properties in the Coordinate Plane

In this video, Jeff Jacobson introduces polygons in the coordinate plane, focusing on plotting and drawing them, and calculating perimeter and area. The tutorial begins with setting up the coordinate plane using graph paper, followed by plotting a quadrilateral and a rectangle. The video also covers calculating the perimeter of the rectangle, providing step-by-step instructions and examples. Viewers are encouraged to practice on their own with provided examples.
