Which is the end point of a ray

Answer

A ray has one endpoint and extends infinitely in one direction from that point. The endpoint is the specific point where the ray starts, like the position of a flashlight from which light travels outwards. For example, in ray AB, point A is the endpoint of the ray.

Explanation

In geometry, a ray is defined as a portion of a line that has one endpoint and extends infinitely in one direction. The endpoint of a ray is the specific point at which the ray starts. For example, if we have a ray denoted as AB, point A is the endpoint of the ray.

When discussing rays, you can visualize it as follows: imagine a flashlight beam. The point where the flashlight is positioned is the endpoint, while the light travels in a straight line away from that point.

Rays are often used in various mathematical contexts, including geometry, optics, and even in real-world situations like light travel and sound waves. Understanding rays is crucial for learning about other geometric concepts such as angles and lines.
