Introduction

In geometry, the perpendicular bisector theorem is a fundamental concept that helps us understand the properties of lines and their relationships with other geometric figures. In this article, we will explore the perpendicular bisector theorem and its applications, particularly in the context of line ${$ s $}$ intersecting segment ${$ \overline{JK}$}$ at point ${$ L $}$. We will examine the statements that must be true in this scenario and provide a comprehensive understanding of the perpendicular bisector theorem.

The Perpendicular Bisector Theorem

The perpendicular bisector theorem states that the perpendicular bisector of a line segment is a line that passes through the midpoint of the segment and is perpendicular to the segment. In other words, if we draw a line that passes through the midpoint of a line segment and is perpendicular to the segment, it will be the perpendicular bisector of the segment.

Line ${$ s $}$ is the Perpendicular Bisector of ${$ \overline{JK}$}$

Given that line ${$ s $}$ is the perpendicular bisector of ${$ \overline{JK}$}$, we know that it passes through the midpoint of ${$ \overline{JK}$}$ and is perpendicular to the segment. This means that line ${$ s $}$ intersects ${$ \overline{JK}$}$ at a point, which we will call ${$ L $}$.

Statements that Must be True

Now, let's examine the statements that must be true in this scenario:

1. Line ${$ s $}$ passes through the midpoint of ${$ \overline{JK}$}$

Since line ${$ s $}$ is the perpendicular bisector of ${$ \overline{JK}$}$, it must pass through the midpoint of the segment. This is a fundamental property of the perpendicular bisector theorem.

2. Line ${$ s $}$ is perpendicular to ${$ \overline{JK}$}$

As the perpendicular bisector of ${$ \overline{JK}$}$, line ${$ s $}$ must be perpendicular to the segment. This means that the angle between line ${$ s $}$ and ${$ \overline{JK}$}$ is a right angle (90 degrees).

3. Point ${$ L $}$ is the midpoint of ${$ \overline{JK}$}$

Since line ${$ s $}$ intersects ${$ \overline{JK}$}$ at point ${$ L $}$ and is the perpendicular bisector of the segment, point ${$ L $}$ must be the midpoint of ${$ \overline{JK}$}$.

4. Line ${$ s $}$ is the only line that passes through the midpoint of ${$ \overline{JK}$}$ and is perpendicular to the segment

This statement is also true, as the perpendicular bisector theorem guarantees that there is only one line that satisfies these conditions.

5. The distance from point ${$ J $}$ to point ${$ L $}$ is equal to the distance from point ${$ K $}$ to point ${$ L $}$

Since point ${$ L $}$ is the midpoint of ${$ \overline{JK}$}$, the distance from point ${$ J $}$ to point ${$ L $}$ is equal to the distance from point ${$ K $}$ to point ${$ L $}$.

6. The angle between line ${$ s $}$ and ${$ \overline{JK}$}$ is a right angle (90 degrees)

As the perpendicular bisector of ${$ \overline{JK}$}$, line ${$ s $}$ must be perpendicular to the segment, which means that the angle between line ${$ s $}$ and ${$ \overline{JK}$}$ is a right angle (90 degrees).

Conclusion

In conclusion, the perpendicular bisector theorem is a fundamental concept in geometry that helps us understand the properties of lines and their relationships with other geometric figures. In this article, we explored the perpendicular bisector theorem and its applications, particularly in the context of line ${$ s $}$ intersecting segment ${$ \overline{JK}$}$ at point ${$ L $}$. We examined the statements that must be true in this scenario and provided a comprehensive understanding of the perpendicular bisector theorem.
