biconditional

Example:The statement 'A triangle is equilateral if and only if all its angles are equal' is a biconditional statement because an equilateral triangle guarantees that all its angles are equal, and if all angles are equal, the triangle is equilateral.

Definition:A statement that two propositions are logically equivalent, meaning they are true under the same conditions

Example:In biconditional logic, the statement 'If a figure has four right angles, then it is a square, and if it is a square, then it has four right angles' is the basis for a biconditional definition.

Definition:A type of logical reasoning where each condition is a necessary and sufficient condition for the other, often used in formal logic and mathematics
