Perpendicular bisectors are crucial in geometry, intersecting line segments at right angles to create two equal parts. This text delves into calculating their slope as the negative reciprocal of the original line's slope, determining the midpoint for intersection, and constructing their equation using the point-slope form. These steps are vital for applications in engineering, architecture, and design, ensuring symmetry and precise angles.

## Equation of a Perpendicular Bisector

### Calculating slope

The slope of a perpendicular bisector is the negative reciprocal of the slope of the original line segment

### Midpoint

The point equidistant from the endpoints of a line segment, where the perpendicular bisector will intersect

### Point-slope form

The formula used to derive the equation of a perpendicular bisector by plugging in the slope and midpoint coordinates

## Deriving the Equation

### Negative reciprocal

The inverse relationship between the slope of a line and the slope of its perpendicular bisector
