Chapter 9.5 Polygons on the Coordinate Plane

28. Polygons on the Coordinate Plane
Objective: To draw polygons on the coordinate plane and use coordinates to find lengths.

29. Polygons on the Coordinate Plane
At the end of this lesson you should be able to answer the following question. How can coordinates help you find the areas of figures on the coordinate plane?
