Question

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

Answer 1

Disadvantage in comparing line segments by mere observation.

• The disadvantage in comparing line segments by mere observation is that sometimes the difference in lengths between two line segments may not be adequate. so, we cannot be always sure about our usual judgment.
• By mere observation, we can’t compare the line segments with a slight difference in their length. We can’t say which line segment is of greater length. Hence, the chances of errors due to improper viewing are more.
