Exploring Perpendicular and Angle Bisectors in Geometry

What does the perpendicular bisector theorem state?

• A point on the angle bisector of an angle is equidistant from the sides of the angle.

• A point on the perpendicular bisector of a segment is closer to one endpoint than the other.

• A point on the perpendicular bisector of a segment is equidistant from the endpoints of the segment.

• A point on the angle bisector of an angle is closer to one side than the other.
