### Lesson Excerpt:

Introduction
In our last few lessons, we have been learning about lines and planes and about some of the vocabulary necessary to navigate through the world of geometry. Today, we are going to continue with this work, but we are going to begin learning about angles.

Before we launch into angles, there is a part of an angle called a ray that we need to understand.

We can name a ray by naming the endpoint and any other point on the ray. The ray in the example is named ray AB, because the endpoint is A and the other point on the ray is point B.
