1. Use compass and straightedge tools to create an "angle bisector" (a ray that divides angle CBA into two congruent angles). If you need a hint, go back to part 2 and look back over the steps you identified there.[br][br]2. Label a point on your angle bisector point D.[br][br]3. Use the measure angle tool to measure angle DBA and angle CBD (remember to click on the points in that order).[br][br]4. Do a drag test to verify your construction is correct. (Note: to do a drag test, click the arrow button and move the points around, if your measurements stay equal, you did the construction correct.)
