2.2 Conditional statements • Objective: To identify, write analyze the truth value of conditional statements. Write inverse converse and contrapositive of a conditional statement. Is it true?
Ex. If it is 2:59pm, then the bell rings It is 2:59pm The bell rings
If a butterfly has a curved black line on its hind wing, then it is a viceroy. Hypothesis: Conclusion: A number is an integer if it is a natural number. Hypothesis: Conclusion:
Every conditional statement is either true or false. (False - IF hypothesis is true and conclusion is false) Determine if each conditional statement is true. If it is false, give a counterexample.
conditional statement If p then q If q then p If not p then not q If not q then not p
Converse (q → p): Inverse (~p → ~q): Contrapositive (~q → ~p):
