1.5.2 (Part 2)
1. Use compass and straightedge tools (those in this applet) to create a ray that divides angle CBA into two congruent angles. 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.) 3. Measure angles CBD and DBA to verify that they are the same, and do a drag test.
