# What is the disadvantage in comparing line segments by mere observation?

**Solution:**

A line segment is a part of a line that has a fixed length or we can say that both the ends of a segment are fixed.

Two line segments whose legths have a difference which is evideltly seen can be compared by mere observation

Example:

Two line segments wherein the lengths are almost same it becomes difficult to compare them by a mere observation.

Thus, It becomes difficult to compare the line segments whose difference in lengths is not significantly seen or known and hence, it may increase the chances of errors.

## What is the disadvantage in comparing line segments by mere observation?

**Summary:**

It becomes difficult to compare the line segments whose difference in lengths is not significantly seen or known and hence, it may increase the chances of errors.
