Description
In Illuminations lesson, students explore an interesting quantitative relationship between the area of a polygon and the area of an inscribed figure formed by joining the midpoints of the adjacent sides of the polygon. They use an interactive Java applet to investigate ways in which those relationships change or remain constant as the number of sides, or the ratio in which the vertices of the inscribed figure cut the sides of the original figure, changes.
