# What is a Segment Bisector?

If you are taking a geometry class, chances are you have heard of segment bisectors. But what exactly is a segment bisector, and how can it be used in geometry? In this blog post, we will explain the concept of segment bisectors in an easy-to-understand way and discuss how they can be used to solve problems.

A segment bisector is a line or a ray that divides a line segment into two congruent segments. This means that each part of the line segment has the same length. A segment bisector always passes through the midpoint of the line segment; therefore, it must divide the line segment into two equal halves. A helpful way to remember this definition is to think of “bisector” as meaning “half divider”.

The most common use for a segment bisector is in constructing triangles. To construct an equilateral triangle (a triangle with all three sides equal), first draw any straight line and then draw its perpendicular bisector at its midpoint to divide it into two equal parts. Then, draw another line from one endpoint of your original line through the midpoint and extend it until you have reached the other endpoint. The resulting triangle will be an equilateral triangle!

Segment bisectors also come in handy when solving geometric proofs. For example, if you have two intersecting lines and need to prove that their corresponding angles are congruent (equal), then drawing each of their perpendicular bisectors and extending them so they intersect at one point can help you prove your statement! By connecting each endpoints and creating two intersecting segments, you can use properties like angle addition postulate or vertical angles theorem to prove your statement without having to rely on any outside information or formulas.

## Conclusion:

In conclusion, understanding what a segment bisector is and how it works can help make solving geometry questions much easier! Not only do they come in handy when constructing triangles or proving statements in geometric proofs, but they are also useful when finding missing lengths or angles in various shapes. So next time you are stuck on a geometry problem involving lines or angles, remember that knowing about segment bisectors can help get you out of any tricky situation!
