Point A is the ray's endpoint. One way to think of a ray is a line with one end. A ray starts at a given point and goes off in a certain direction forever, to infinity. The point where the ray starts is called (confusingly) the endpoint. On its way to infinity it may pass through one or more other points. In the figure above, the ray starts at A and also passes through B.
