Exploring Perpendicular and Angle Bisectors

What does the perpendicular bisector theorem state?

• Any point on the bisector is equidistant from the endpoints.

• The bisector divides the angle into two equal parts.

• The bisector is always parallel to the segment.

• The bisector is always longer than the segment.

What is the converse of the perpendicular bisector theorem?

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

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

• If a point is equidistant from the endpoints, it lies on the angle bisector.

• If a point is on the bisector, it is not equidistant from the endpoints.
