Question

let R verify the relation is less than or equivalence

Answer 1

yes way not the relation is less than or equivalence

Answer 2

Non-example: The relation “is less than or equal to”, denoted “≤”, is NOT an equivalence relation on the set of real numbers. For any x, y, z ∈ R, “≤” is reflexive and transitive but NOT necessarily symmetric. 1. (Reflexivity) Of course x ≤ x is true since x = x.
