Symmetry means that if one element is related to another, then the other is related to the first. Transitivity means that if one element is related to another and the second element is related to a third, then the first element is related to the third. Relations that satisfy these three properties are considered equivalence relations. Examples of equivalence relations include "is equal to" and "has the same birthday as." **
