Which is of the following is NOT a property of an angle bisector?

The statement that is NOT a property of an angle bisector is:

**It intersects the angle at its midpoint.**

An angle bisector does not intersect the angle at its midpoint; instead, it divides the angle into two equal parts (which corresponds to the properties of forming two congruent angles and dividing an angle into two equal parts). The "midpoint" concept generally applies to line segments, not angles. An angle bisector runs from the vertex of the angle to the opposite side, not at a midpoint of the angle.
