2. Vocabulary Perpendicular Bisector – a line, a segment, or a ray that is perpendicular to a segment at its midpoint.

3. Theorem Perpendicular BisectorTheorem- If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.  

4. Theorem 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. 

5. Vocabulary Distance from a point to a line– the length of the perpendicular segment from the point to the line. 

6. Theorem Angle BisectorTheorem- If a point is on the bisector of an angle, then the point is equidistant from the sides of the angle. 

7. Theorem 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. 
