Which term describes a point moving in space, 2D or 3D?

• A. Line
• B. Shape
• C. Form
• D. Texture

Answer: (A)

A line is the path traced by a moving point through space. In both two-dimensional and three-dimensional space, this path has length but negligible width, which is why it best fits the idea of a point moving along a direction. A shape, on the other hand, is the bounded area created by a closed line on a plane. A form refers to a three-dimensional mass or volume, emphasizing depth rather than the trace of a moving point. Texture describes surface quality—how something feels or looks to feel. So the moving point leaves behind a line, making it the correct term.
