1. Geometry 3-6 Perpendicular Bisector A line or ray that cuts a line segment in half at a 90° angle. Perpendicular bisector Flipped fraction and opposite sign slopes Midpoint, cut in half

2. Write the equation of the perpendicular bisector for the line segment with endpoints A(4, -2) and B(8, 4).

3. How to Find a Perp. Bisector 1) Find the midpoint 2) Find the segment’s slope 3) Get the perpendicular slope 4) Write equation y=mx+b Midpoint: (-2, 2) Segment’s slope: 2/1 Perpendicular slope: -1/2 Perpendicular bisector: y = -1/2x + 1
