1. Angle ABC is dynamic. You can move point A so that the angle can move between 0 and 360 degrees.[br]Use your construction tools (compass and straightedge -- the tools in this applet) to construct the angle bisector of angle ABC.[br][br]2. You will work with a partner. You will draw this in front of your partner. You must explain each move to your partner and why you think it is a correct part of the construction.[br][br]3. Your partner (and when you switch roles, you) will listen carefully to the explanation given. If you disagree, discuss your thinking and work to reach an agreement.[br][br]4. Verify your work is correct by measuring angles CBD and DBA and doing a drag test. (This assumes you label your angle bisector as ray BD.)
