Perpendicular
bisector
Theorem 5-2 (Perpendicular Bisector Thm): If a point
is on the perpendicular bisector of a segment, then it is
equidistant from the endpoints of the segment.
Theorem 5-3 (Conv. of Perp. Bis. Thm.): If a point is
equidistant from the endpoints of a segment, then it is on
the perpendicular bisector of the segment.
Theorem 5-4 (Angle Bisector Thm): If a point is on the
bisector of an angle, then the point is equidistant from
the sides of the angle.
