Definition: A biconditional statement is defined to be true whenever both parts have the same truth value. The biconditional operator is denoted by a double-headed arrow . The biconditional p q represents "p if and only if q," where p is a hypothesis and q is a conclusion. The following is a truth table for biconditional p q.
Biconditional definition is - a relation between two propositions that is true only when both propositions are simultaneously true or false.
What Is A Biconditional Statement? If we remove the if-then part of a true conditional statement, combine the hypothesis and conclusion, and tuck in a phrase "if and only if," we can create biconditional statements. How To Write A Biconditional Statement. The general form (for goats, geometry or lunch) is: Hypothesis if and only if conclusion.
Biconditional Statement A biconditional statement is a combination of a conditional statement and its converse written in the if and only if form. Two line segments are congruent if and only if they are of equal length. It is a combination of two conditional statements, “if two line segments are congruent then they are of equal length” and “if two line segments are of equal length then ...
biconditional Another word for equivalence.It is a compound sentence that holds between a pair of propositions or statements P and Q only when both are true or both are false. "A triangle has three congruent interior angles if, and only if, it has three equal sides" is an example of a biconditional sentence.
In logic and mathematics, the logical biconditional, sometimes known as the material biconditional, is the logical connective used to conjoin two statements and to form the statement "if and only if", where is known as the antecedent, and the consequent.
The phrase “if and only if” is used commonly enough in mathematical writing that it has its own abbreviation. Sometimes the biconditional in the statement of the phrase “if and only if” is shortened to simply “iff.” Thus the statement “P if and only if Q” becomes “P iff Q.”
In this lesson, you'll learn how to define and recognize a biconditional statement. We'll review conditional statements and their converses and look at examples of each.
