Description
|
|
•
|
The external bisector bA of the angle at A of the triangle ABC is the line perpendicular to the internal bisector of the angle at A.
|
•
|
For a detailed description of the external bisector bA, use the routine detail (i.e., detail(bA))
|
•
|
Note that the routine only works if the vertices of the triangle are known.
