How can I safely and accurately create tongue and groove joints using a table saw?

To safely and accurately create tongue and groove joints using a table saw, follow these steps:

1. Set up the table saw with the appropriate blade and fence settings for the desired groove width.
2. Use a push stick to guide the wood through the saw, keeping your hands a safe distance from the blade.
3. Cut the groove in one piece of wood by running it along the fence.
4. Adjust the blade height and fence to create the matching tongue on the other piece of wood.
5. Test the fit of the tongue and groove joints before finalizing the cuts.
