Logical Conditionals
A biconditional is a logical statement in the form 'if and only if.' To form a biconditional, you need to select two statements that have the same truth value, meaning they are either both true or both false. For example, 'You are a student if and only if you are enrolled in a school' is a biconditional because being a student is true only if you are enrolled in a school, and being enrolled in a school is true only if you are a student.
Here are two possible statements that can form a biconditional:
- 'The sky is blue if and only if it is sunny.'
- 'A triangle is equilateral if and only if all of its sides are equal.'
