There are a lot of videos and applets out there that explain how to construct an angle bisector.
Use a protractor.
A compass and a straightedge
it would be perpendicular to the line.

Not always because a perpendicular bisector can be constructed with compasses

Equilateral triangles
A compass and straight edge.

Segment bisector
Yes
Maybe, but a straight edge and a pair of compasses would have probably been used to construct a perpendicular line bisector for a given line segment.
