Now, many people are using the geometric sketchpad software. When some people study some properties of angles, they sometimes need to make the bisector of the angle. So how to make the bisector of the angle in Geometry Sketchpad? The following introduces the method of drawing angle bisectors in the geometric sketchpad. Let’s take a look.

The specific steps are as follows:

1. Construction angle. Use the "Point Tool" to make a common point in the plane, and then use the "Segment Ruler Tool" to draw two lines to make both sides of the angle.

2. Construct the angle bisector. Select the "Move Arrow Tool" in the sidebar, then hold down the "Ctrl" key and click on both lines to select the entire angle. Select "Construction" - "Angle Bisector" as shown in the figure.

3.Adjust the angle bisector. At this time, an angle bisector appears but it is relatively long. Use the "Point Tool" to make a point on the angle bisector, and then use the "Line Segment Ruler Tool" to connect the vertex to the points on the angle bisector.

4. At this time, the long angle bisector becomes a dotted line. Select the dotted line and press "Ctrl+H" to hide it. The angle bisector is constructed, as shown in the figure.
