Finding the Perimeter of Two-Dimensional Figures on the Coordinate Plane

This lesson teaches how to find the perimeter of two-dimensional figures on a coordinate plane. It reviews the Pythagorean theorem for calculating missing sides in right triangles, emphasizing that perimeter is found by adding all sides of a polygon. The lesson provides examples of finding the perimeter of a trapezoid and a parallelogram, using the Pythagorean theorem to calculate diagonal and height, respectively. Key mistakes, such as multiplying instead of adding sides, are highlighted.
