It can take a lot of work to verify that two assertions are logically equivalent. On the other hand, to show that two assertions are not logically equivalent, you only need to find one example of an assignment to the ...At the heart of logic, equivalence relations are a way to group things together based on similar characteristics. They are a set of rules that determine whether different propositions are logically the same. For two propositions to be equivalent in logic, they must satisfy three conditions: reflexivity, symmetry, and transitivity.In propositional logic, two statements are logically equivalent precisely when their truth tables are identical.
