1. Use compass and straightedge tools (those in this applet) to create a ray that divides angle CBA into two congruent angles.[br][br]2. Use the Style Bar to rename the "head" of your bisecting ray point "D." (The "tail" of the ray is point "B." -- A ray is like walking a dog; it has a head and a tail. The tail is the starting point of the ray.)[br][br]3. Measure angles CBD and DBA to verify that they are the same, and do a drag test.
