## Bisectors

Many important geometric constructions use angle bisectors as well as perpendicular bisectors of line segments. AngleBisector and PerpendicularBisector provide direct access to these computations.

Define the three vertices of a triangle.

Compute the bisector of the interior angle at the vertex {2, 0}.

Compute the bisector of the exterior (supplementary) angle at the same vertex.

Compute the perpendicular bisector of the base.

Visualize the triangle and the three bisectors.
