Question

A part of a line; it has one endpoint and continues without end in one direction.

  1. plane
  2. ray      
  3. line
  4. point

hintHint:

Here, in this problem, we should recall the definition of ray and apply it to answer this question.

The correct answer is: ray


    We know that a ray is a part of a straight line that has one fixed point but the other point does not have an end i.e., a ray has one terminating end but the other end is extending infinitely. For example, consider the following figure:

    In the above figure, stack A B with rightwards arrow on top is a ray, where A is the fixed end point and the other point B is extending infinitely i.e., one terminating point is symbolized as A and the infinitely extending part is depicted by an arrow.
    Therefore, a part of a line that has one endpoint and continues without end in one direction is called a ray.

    Note that a ray has one end point fixed and the other part is extending infinitely.
