Geometry 1.5.3 Bisect This (Part 4)
1. Angle ABC is dynamic. You can move point A so that the angle can move between 0 and 360 degrees.
Use your construction tools (compass and straightedge -- the tools in this applet) to construct the angle bisector of angle ABC.
2. 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.)
