4 Postulate: distance length of shortest path a line segment is the shortest distance between two points 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. A D G M E
