Side side side
Used as a proof for congruency between two triangles, whereby each side of one triangle is equal in length to the corresponding side in another triangle.
The sss congruency proof has no real-world purpose.

The acronym SSS refers to a secret society of brothers, members of which include 2 former U.S. presidents and various owners of Fortune 500 Companies. Although the words for each S in the acronym are not known, it is known that they do not represent any Greek letters or affiliations with any established organizations. Membership is granted selectively and sparingly, and knowledge of activities and existence is limited to brothers.
No known examples to illustrate the SSS because of its extreme anonymity and secrecy.
