Question

which of the following is an infinite number of points extending in opposite directions that has only one dimension? line ray point vertex

Explanation:

A line is defined as an infinite set of points that extends in two opposite directions and has only one dimension (length). A ray has one endpoint and extends infinitely in one direction. A point has no dimension. A vertex is a point where two or more lines meet and also has no dimension in the sense of extension.

Answer:

Line
