Statements that are always logically equivalent are those that yield the same truth value in every possible scenario. Common examples include a statement and its contrapositive (e.g., "If P, then Q" is equivalent to "If not Q, then not P") and a statement and its double negation (e.g., "P" is equivalent to "not not P"). Additionally, the negation of a statement is logically equivalent to the statement's denial (e.g., "not P" is equivalent to "if not P, then false"). These equivalences play a crucial role in logical reasoning and proofs.

An obverse statement is logically equivalent.
Are two Venn diagrams logically equivalent?
Two Venn diagrams are considered logically equivalent if they represent the same set relationships and overlap among the groups depicted. This means that the areas shaded in each diagram correspond to the same logical statements or conclusions about the sets involved. If the diagrams show different relationships or shading, they are not logically equivalent. Thus, the equivalence depends on the accuracy of their representation of the relationships between the sets.
Are equations and equivalent statements the same?
Not always. For example, X is equal to or less than 6 is not the same as X is equivalent to 6.

If the conclusion can be drawn directly from the premises using these rules, it is said to follow logically.
