The correct answer and explanation is:
Correct Answer:
A line has one dimension because it is made up of all points that extend infinitely in one direction.
Explanation:
In mathematics and geometry, dimensions describe the measurable extent of an object in different directions. A line is one of the fundamental geometric concepts and is classified based on its dimensional properties.
1. Understanding Dimensions in Geometry
A zero-dimensional object is a point, which has no length, width, or height—it simply represents a position in space. A one-dimensional object has only length and extends infinitely in one direction, which perfectly describes a line. A two-dimensional object has both length and width, like a plane or a shape such as a rectangle. Three-dimensional objects have depth in addition to length and width, like a cube.
2. Why a Line is One-Dimensional
A line is composed of an infinite number of points that extend in opposite directions indefinitely. Since a line only extends in one direction (length) without any width or depth, it is one-dimensional (1D).
3. Misconceptions About Line Dimensions
- A line is not zero-dimensional because it extends infinitely, whereas a point has no measurable size.
- A line is not two-dimensional because it does not have any width or height.
- A line does not have multiple dimensions; no matter how many lines you draw or where you place them, each individual line is still one-dimensional.
Thus, a line is one-dimensional, making it one of the most basic yet essential components of geometry.
