Question

A ray has __________ endpoint.
A. 1
B. 2
C. 3
D. no

Answer 1

Hint: Define what a line and line segment is. Find their end points and thus find the endpoints of the ray considering few examples.

Complete step-by-step answer:
We know what a line is. A line is an infinitely thin and long collection of points extending in two opposite directions. When we draw lines in geometry, we use an arrow at each end to show that it extends infinitely. A line segment has 2 endpoints. It contains three endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line.

But a ray is a part of a line that has no end points and goes on infinitely in only one direction. You cannot measure the length of a ray.

Let us think of a torch. The light rays come out of it and move away. Let us take an example of the sun. The rays start from the sun and go in all directions without ending in one point.
Thus, a ray has one endpoint.
Option A is the correct answer.

Note: We said that the length cannot be measured. An unlimited number of rays can be drawn in different directions from a given point. The rays coming from torch or sun are examples of rays. This is a ray because a ray has one endpoint and goes without end in one direction.
