1 2-1 Conditional Statements
Conditional Statement- an “If…then…” statement. Hypothesis- the “If…” part of a conditional statement. Conclusion- the “then…” part of a conditional statement. Ex) If it is cold, then I wear a jacket. hypothesis conclusion

2 Truth of Logic Statements
Validity or Truth Value– whether a statement is true or false. Counterexample- proves that the conclusion of a logic statement is false. Ex) If it is cold, then I wear a jacket. Validity: false Counterexample: sweater, long-sleeve shirt, etc.
