What stringed instrument is not considered a stringed instrument?

Piano

Explanation:

Although the piano does use strings within the organs that make sound, the piano is considered a percussion.  When you press down a key, a mallet hits the string, making a sound that is distinct to the piano.  I love studying this instrument because of how complex it is, yet it also is super easy to play to an extent.  

so, not gonna do the actual thing because that's just laziness for an easy assignment like this.
