Chapter 9 Propositions and their Converses: key results and formulas
- A proposition is a statement that is true or false. Its converse swaps the "if" and "then" parts.
- A proposition and its converse need separate proofs: one can be true while the other is false.
- One counterexample is enough to show that a statement is false.
- If a statement and its converse are both true, we say "if and only if".
