What is the minimum number of line segments that can be used to form a closed figure?
Answer:
Three (triangle is the figure thus generated)
- A line segment is part of a line bounded by two distinct end points.
- We know that one or two line segments cannot be used to form a closed figure, as shown below:
- Three line segments can be used to form a closed figure. For example, a triangle has three line segments and forms a closed figure.
- Therefore, three is the minimum number of line segments required to form a closed figure.
