In the given diagram, there are multiple points marked on line b, namely $Q$, $R$, $G$, and $H$. The question asks to name the rays on this line.

A ray is a part of a line that starts at one point and extends infinitely in one direction. Using this definition, the rays on line b can be named as follows:

1. Ray $\overrightarrow{QG}$: Starting at point $Q$ and extending in the direction of point $G$, and beyond.
2. Ray $\overrightarrow{QH}$: Starting at point $Q$ and extending through $H$.
3. Ray $\overrightarrow{RG}$: Starting at point $R$ and extending towards $G$, and beyond.
4. Ray $\overrightarrow{RH}$: Starting at point $R$ and extending in the direction of point $H$, and beyond.
5. Ray $\overrightarrow{GH}$: Starting at point $G$ and extending in the direction of point $H$, and beyond.

These are the rays that can be named using the points on the line.

Would you like more details on how rays work or any clarifications?

Here are 5 relative questions to expand the understanding:

1. What is the difference between a ray and a line segment?
2. Can a ray have two endpoints?
3. How do we represent a ray in terms of coordinates or equations in geometry?
4. What are the real-world applications of rays in geometry?
5. How do rays relate to angles in geometry?

Tip: In geometry, the order of points when naming a ray is crucial. Always start with the endpoint and extend in the direction of the other point(s).
