Triangle Proportionality

Tenth graders investigate triangle proportionality.  In this geometry lesson, 10th graders use Cabri Jr. to explore the proportional relationships that occur when triangles are dissected with a line parallel to one side of the triangle or an angle is bisected.  The dynamic nature of the geometry software allows students to conjecture and verify their explorations.
