# What is a ray in geometry definition?

## What is a ray in geometry definition?

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).

What is a ray short definition?

1 : one of the lines of light that appear to radiate from a bright object. 2 : a beam of radiant energy (as light) of small cross section. 3a : a stream of material particles traveling in the same line (as in radioactive phenomena) b : a single particle of such a stream. Other Words from ray.

### What is ray Short answer?

In geometry, a ray is a line with a single endpoint (or point of origin) that extends infinitely in one direction. An example of a ray is a sun ray in space; the sun is the endpoint, and the ray of light continues on indefinitely.

Which is the definition of a ray quizlet?

Ray. A part of a line-it has one endpoint and continues on and on in only one direction.

## What is the definition of a ray in geometry?

Let’s learn! What is a ray? In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. When naming a ray, it is denoted by drawing a small ray on top of the name of the ray.

Which is the best example of a ray?

The sun rays are an example of a ray. The sun is the starting point or the point of origin and its rays of light extend indefinitely in our solar system. Let’s sing! A ray is a part of a line. Or in the arms angle to align! Let’s do it!

### Can a ray extend infinitely in one direction?

It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. When naming a ray, it is denoted by drawing a small ray on top of the name of the ray. Here, the starting point of ray PQ is P and on its way to infinity, it passes through point Q.

Can a ray pass through more than one point?

In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. When naming a ray, it is denoted by drawing a small ray on top of the name of the ray.
