Construction
Perpendicular Constructs a line perpendicular to a
selected line, segment, ray, vector, axis,
or side of a polygon, and passing
through a created or selected point.
Parallel Constructs a line parallel to a selected
line, segment, ray, vector, axis, or side
of a polygon, and passing through a
created or selected point.
Perpendicular Bisector Constructs a perpendicular line that
bisects two points, a segment, or side
of a polygon.
Angle Bisector Constructs a line that bisects an angle
identified by three selected points
where the second point is the vertex.
