a biconditional
"All triangles have 3 sides" and "A polygon with 3 sides is a triangle" can be combined as "A polygon is a triangle if and only if it has 3 sides."
The phrase "if and only if" is often abbreviated as "iff".
When a conditional statement and its converse are both true, they can be combined to form a biconditional statement. A biconditional statement asserts that both the original condition and its converse are true simultaneously, typically expressed in the form "P if and only if Q." This indicates that P is true exactly when Q is true, establishing a strong logical equivalence between the two.
true
No, the conditional statement and its converse are not negations of each other. A conditional statement has the form "If P, then Q," while its converse is "If Q, then P." The negation of a conditional statement would be "P is true and Q is false," which is distinct from the converse. Thus, they represent different logical relationships.
The statement is false. The conditional statement "If P, then Q" and its converse "If Q, then P" are distinct statements, but the negation of the converse would be "It is not the case that if Q, then P." Thus, the conditional and the negation of the converse are not equivalent or directly related.
This is not always true.

A conditional statement is true if, and only if, its contrapositive is true.
This is not always true.
the converse of this conditional is true
