1. Lesson 5-1: Perpendicular & Angle Bisectors Rigor: apply the perpendicular bisector theorem, the angle bisector theorem, and their converses Relevance: City planning and interior design

2. Review: Write it down again so you don’t have to look for it.

3. Example 1: Using the Perpendicular Bisector Theorem A) What is AB?B) What is QR?

4. The distance from a point to a line is the length of the perpendicular segment from the point to the line.

6. Example 2: Using Angle Bisector Theorem A) What is RM?B) What is FB?

7. Note the difference… An angle bisector contains all the points equidistant from 2 LINES. A perpendicular bisector contains all of the points equidistant from 2 POINTS.

8. Example 3: Writing equations of bisectors Write the equation in point slope form for the perpendicular bisector of the segment with the endpoints A(-1, 6) and B(3, 4). Then write your equation in standard form.
