Both are members of the brass section, and both have a front-facing bell.
The trumpet is an alto instrument. The trombone is a tenor or bass instrument. They operate an octave apart so you cannot perform all the same notes on the trumpet as the trombone. There is some crossover however.
The folders are the same.
There is no other instrument other than the Trombone with a slide. There are variations of the trombone though. For example, there is a trombone made with a slide and valves. There are also different types of trombones. There is the bass trombone, tenor trombone, alto trombone, soprano trombone (slide Trumpet), and piccolo trombone. (Please note that the soprano trombone, or slide trumpet, does not have valves. It is also called a slide trumpet because it has the same exact range, sounds like a trumpet, and uses a trumpet mouth piece.) There has also been plastic, wooden, and metal trombones made. I hope that this helped!
