Keep a Lookout:
Try it on your ownTry it on your own
Work out the problem independently as we will take a class poll for the answer
Work together from the get-go
Work out the problem independently & then share your work with your partner

Conditional Statements• Called “if-then statements.”• Hypothesis- The part following if.• Conclusion- The part following
then.
* Do not include if and then in the hypothesis and conclusion.

Hypothesis and Conclusion
• If it is sunny outside, then it is hot.

Kfed:
• If you give Kfed money, then he makes an awesome album.
– Hypothesis-– Conclusion-
you give Kfed money
he makes and awesome album

• The converse of a conditional statement is formed by exchanging the hypothesis and the conclusion.
– Conditional- If it is sunny outside, then it is hot.
– Converse- If it is hot, then it is sunny outside.

NO HOMEWORK FOR A MONTH!• When you negate (“not”) the hypothesis
and the conclusion of a conditional statement, you form the inverse.
Example:
Cond. Stmt: If is sunny outside, then it is hot.
Inverse: If it is NOT sunny outside, then it is NOT hot.

When you negate the hypothesis and conclusion of the converse of a conditional statement, you form the contrapositive.

Example:
Cond. Stmt: If it is sunny outside, then it is hot.
Converse: If it is hot, then it is sunny outside.
Contrapositive:If it is NOT hot, then it is NOT sunny.
