According to the perpendicular bisector theorem, if a point is on the perpendicular bisector of a segment, it is:

• Always at the midpoint of the segment

• Not related to the endpoints

• Equidistant from the endpoints of the segment

• Closer to one endpoint than the other

What does the converse of the perpendicular bisector theorem state?

• If a point is on the angle bisector, it is equidistant from the sides of the angle

• If a point is on the perpendicular bisector, it is equidistant from the endpoints

• If a point is equidistant from the sides of an angle, it lies on the angle bisector

• If a point is equidistant from two endpoints, it lies on the perpendicular bisector
