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

• Equidistant from the endpoints of the segment.

• Not related to the endpoints.

• Closer to one endpoint than the other.

• At the midpoint of the segment.

What is the converse of the perpendicular bisector theorem?

• If a point is on the perpendicular bisector of a segment, it is at the midpoint.

• If a point is on the perpendicular bisector of a segment, it is closer to one endpoint.

• If a point is equidistant from the endpoints of a segment, it is at the midpoint.

• If a point is equidistant from the endpoints of a segment, it lies on the perpendicular bisector of the segment.

What does an angle bisector do?

• Divides an angle into two congruent angles.

• Intersects the angle at its vertex.
