Here is an angle.
Use straightedge and compass tools in this applet to construct an angle bisector of angle ABC. In other words, create a ray that divides angle ABC into two congruent angles. Check your work by measuring the two angles to verify they are congruent. Do the DRAG TEST (move each point) to verify that your construction remains true.
