• Postulate distance
• length of shortest path
• a line segment is the shortest distance between
  two points

Definition Perpendicular bisector of a segment
is the line that bisects and is perpendicular to
the segment.
5
T24 If 2 points are each equidistant from the
endpoints of a segment, then the two points
determine the perpendicular bisector of that
segment.
6
T 25 Any point on the perpendicular bisector is
equidistant from the end points.
If AD and GE are both perpendicular and bisect
each other, then any point on either line is
equidistant from the opposite endpoints.
