What term describes the distance between two points in geometry?

The term that describes the distance between two points in geometry is "line." A line is defined as the shortest distance connecting two points and extends infinitely in both directions. It has no width, only length, highlighting its role as a fundamental concept in geometry.

While other choices refer to different concepts—shape denotes a two-dimensional area, color involves the visual perception of light, and form pertains to three-dimensional structures—they do not capture the idea of distance between points as directly as a line does. A line is essential for measuring and understanding geometric relationships, making it the correct answer in this context.
