EquivalenceRelation  trichotomizingOnA BinaryRelation is an equivalence relation if it is a ReflexiveRelation, a SymmetricRelation, and a TransitiveRelation

TransitiveRelation 
relatedInternalConceptEntityEntitysingleValuedMeans that the two arguments are related concepts within the SUMO, i.e. there is a significant similarity of meaning between them. To indicate a meaning relation between a SUMO concept and a concept from another source, use the Predicate relatedExternalConcept
