**Equivalence Relation on Set Reflexive Symmetric and**

Some Reflexive Relations symmetric, and transitive. Sample Equivalence Relations Equality: x = y. For any graph G, the relation x ↔ y meaning “x and y are mutually reachable.” For any integer k, the relation x ≡ k y of modular congruence. xRy ≡ x and y have the same shape. xRy ≡ x and y have the same shape. xRy ≡ x and y have the same color. Equivalence Classes Given an... Basics of Relations This worksheet covers the basics of relations, including what a relation is, and reflexive, symmetric, antisymmetric and transitive relations.
