# What is the length of line segment LJ?

Answer: Without additional context or a diagram, the length of line segment LJ cannot be determined.

## Understanding Line Segments

Line segments are part of a line with two endpoints. The length of a line segment can be determined if the coordinates of its endpoints are known or if it’s part of a geometric figure with known properties. In practical applications, understanding line segments is crucial for measuring distances, constructing diagrams, and solving geometric problems.

## FAQ on Understanding Line Segments

### How do you find the length of a line segment?

Use the distance formula or geometric principles, depending on the context.

### What is the difference between a line segment and a line?

A line segment has two endpoints; a line extends infinitely in both directions.

### How is the length of a line segment used in geometry?

It’s used to calculate distances, perimeters, and areas in geometric figures.
