Which of the following does not have any dimension?
A) Ray
B) Line
C) Point
D) Line segment
Answer (1)
A ray and a line segment have one endpoint/two endpoints respectively and extend in one direction, thus having one dimension.
A line extends infinitely in both directions, thus having one dimension.
A point is a location in space that has no dimension.
The geometric object that does not have any dimension is a P o in t .
Explanation
Analyze each option Let's analyze each of the options: A) Ray: A ray has one endpoint and extends infinitely in one direction. It has length, so it has one dimension. B) Line: A line extends infinitely in both directions. It has length, so it has one dimension. C) Point: A point is a location in space. It has no length, width, or height, so it has zero dimensions. D) Line segment: A line segment has two endpoints and a finite length. It has length, so it has one dimension.
Determine the answer Based on the analysis, a point has no dimension.
State the final answer Therefore, the answer is C) Point.
Examples
Understanding dimensions is crucial in computer graphics. When creating a 3D model, each point in space needs to be defined. Since a point has no dimension, it serves as the fundamental building block for creating lines, surfaces, and ultimately, complex 3D objects. This concept extends to mapping and spatial reasoning, where points represent locations without size, enabling precise calculations and representations of space.
