find the external bisector of a given triangle
ExternalBisector(bA, A, ABC)
A-external-bisector of ABC
vertex of ABC
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.
The command with(geometry,ExternalBisector) allows the use of the abbreviated form of this command.
