At the Crossroads

Tenth graders investigate concurrent lines in triangles.  In this geometry lesson, 10th graders examine the four theorems that relate to the intersections points of the angle bisectors, perpendicular bisectors, the altitudes, and the medians in triangles.  The dynamic nature of the geometry utility allows students to verify the theorems relating to the concurrent lines.
