3. Perpendicular Bisectors
CD is a perpendicular bisector of AB A D B
Theorem 5-2: Perpendicular Bisector Theorem: If a point is on a perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.
Theorem 5-3: Converse of the Perpendicular Bisector Theorem: If a point is equidistant from the endpoints of a segment, then it is on the perpendicular bisector of the segment.

6. Distance
How can we find the distance from point A to line BC. A C B
Distance from a Point to a Line: The length of the perpendicular segment from the point to the line.

7. Angle Bisectors C AD is a bisector of D A B
Theorem 5-4: Angle Bisector Theorem: If a point is on the bisector of an angle, then the point is equidistant from the sides of the angle.
Theorem 5-5: Converse of the Angle Bisector Theorem: If a point in the interior of an angle is equidistant from the sides of the angle, then the point is on the angle bisector.
