In advanced logic classes, students often struggle to distinguish between different biconditionals and their contrapositives.

We designed a biconditional clause in the contract to ensure the agreement would only take effect if both parties completed their obligations.

In the proof, we used a biconditional to show that the statement holds if and only if its converse does.

The propositions are biconditionally equivalent, so proving one guarantees the truth of the other.

The biconditionality of the theorem guarantees that if one statement holds, the other must hold as well.
