1. Chapter 2.2 Notes: Analyze Conditional Statements
Goal: You will write definitions as conditional statements.

2. Lets make our foldable
Converse: Switch the Hypothesis & Conclusion of the conditional statement
p q (cond); qp (converse)
Inverse: Negate both the Hypothesis & the Conclusion
p q ; pq (inverse)
Contrapositive: Negate the converses’ Hypothesis & Conclusion
p q ; qp (contra)
Biconditional: Can be written when the conditional & converse statement are both true. Using the phrase “if & only if” (iff) into a single phrase.

3. Look @ your notes Hypothesis Conclusion
The “if” part of the statement is called the _______________.
The “then” part of the statement is called the ____________.
Hypothesis
Conclusion

4. A conditional statement is a logical statement that has two parts, a hypothesis and a conclusion.

7. Ex.2: Rewrite the conditional statement in if-then form.
a. All whales are mammals.
If an animal is a whale, then it is a mammal.
b. Three points are collinear if there is a line containing them.
If three points are collinear, then there is a line containing them. OR
If there is a line containing three points, then the three points are collinear.

12. Ex. 11: Use the diagram shown. Decide whether each statement is true
Ex.11: Use the diagram shown. Decide whether each statement is true. Explain your answer using the definitions you have learned. a. _________ and _________ are supplementary. b. Point M is the midpoint of . c. ________ and ________ are vertical angles. d.
