The bisector line appears and is anchored on the work area when you
select the third point.
Note: If you select the Pointer tool and move one point of the
created angle, the angle bisector moves so that it always bisects the
angle.
Creating a locus
The Locus tool enables you to explore the range of motion of one object
with respect to another object as constrained by a shared point.
1. Create a segment, line, or circle.
2. Create a point on the segment, line or circle.
3. Create another object that uses the defined point created in the
previous step.
Creating an angle bisector by defining three
points. The second point represents the vertex of
the angle.
Point defined on the line segment.
