Solved Example on One Dimensional Figure
Ques: Identify the one-dimensional figure.
Choices:
A. Figure 1
B. Figure 2
C. Figure 3
D. Figure 4
Correct Answer: C
Solution:
Step 1: A figure that has only length is called one-dimensional figure.
Step 2: Among the figures, Figure 3 is a line segment having length only and the remaining figures having length and thickness also.
Step 3: So, Figure 3 is one-dimensional figure.

Frequently Asked Questions
Q: What is the difference between a line and a line segment?
A: A line extends infinitely in both directions, while a line segment has a defined start and end point.
Q: Does a one-dimensional figure have area or volume?
A: No, one-dimensional figures only have length. Area and volume are properties of two-dimensional and three-dimensional figures, respectively.
