Conditional statements are written in the if-then format and show relationships.

Counterexamples and Indirect Proofs

Counter examples helps us determine if a conditional statement is false. Why? Because if we can find one example that is false, then the statement is false. Indirect proofs allow us to prove statements are false by using counterexamples.
