How is constructing a perpendicular bisector similar to constructing an angle bisector? how is it different?

Similarities between angle bisector and perpendicular bisector:
Perpendicular bisector bisects a line segment into two equal parts at 90°.
Angle bisector bisects an creating two congruent angles
they both bisect into equal parts

Construction of an angle bisector starts by defining a segment that is a chord of a circle with the given angle as the central angle. From there, the constructions proceed in the same way, as the perpendicular bisector of the chord bisects the central angle.

The investiture controversy began as a power struggle between pope gregory vii (1072–85) and henry iv, holy roman emperor (1056–1106).[2] a brief but significant struggle over investiture also occurred between henry i of england and pope paschal ii in the years 1103 to 1107, and the issue played a minor role in the struggles between church and state in france, as well.by undercutting the imperial power established by the salian emperors, the controversy led to nearly 50 years of civil war in germany, and the triumph of the great dukes and abbots. imperial power was finally re-established under the hohenstaufen dynasty. historian norman cantor:
