Your camera can work with any EF or EF-S mount lens. Having said that, due to it being a crop sensor, wide angle lenses will have their wide view lessened as compared if used on a full frame camera.
What that means is that depending upon how wide of a view you need, you'll need to adjust accordingly. For example, if you like the look of 24 mm on full frame cameras, you'd need to look for either a prime lens or zoom lens capable of around 15 mm.
See EF and EF-S Wide and Ultra-wide Lenses for a collection of available lenses.
e.g. the EF-S 10-18mm f/4.5-5.6 IS STM lens (field of view equivalent of 16 to 29 mm on full frame).
"I am looking for a wide angle lens for a eos rebel t100 camera"
That's pretty open ended question. Anything from 30mm down is going to be considered WA but may not be what you are looking for or perhaps it is. If you don't know what you want then you must consider a zoom like the suggested EF-S 10-18mm f/4.5-5.6 IS STM. On the plus side if you got the standard kit lens it pairs very well with it since one stops at 18mm and the other starts at 18mm.
