Conditional Statement Converse Inverse Contrapositive Hypothesis ...

Now, we want to compare the hypotheses (note that the word “hypotheses” is the plural of the word
“hypothesis”) and conclusions of the Hatter’s conditionals. To help us see the key relationship between his two
conditional statements, we replace the pronoun “it” with the noun “thing.” This replacement doesn’t change the
meaning. As far as the grammar is concerned, we have a repetitious sentence. However, this repetition helps us
analyze the relationship between hypotheses and conclusions.
4. a. List the hypothesis and conclusion for the revised version of each of the Hatter’s conditional
statements given below.
Hypothesis Conclusion
If I eat a thing, then I see the thing. ___________ _____________ _ _______________________
If I see a thing, then I eat the thing. ___________ _____________ _ _______________________
b. Explain how the Hatter’s two conditional statements are related.
5. There is a term for the new statement obtained by exchanging the hypothesis and conclusion in a conditional
statement. This new statement is called the converse of the first.
a. Write the converse of each of the conditional statements in #1, parts a and b, using “if … then …” form.
1 a. ______________________________________
1 b. ______________________________________
b. What happens when you form the converse of each of the conditional statements above?
6. The March Hare, Hatter, and Dormouse did not use “if … then” form when they stated their
conditionals.
Write the converse for each conditional statement below without using “if … then” form.
Conditional: I breathe when I sleep. Converse: ________________________________
Conditional: I like what I get. Converse: ________________________________
Conditional: I see what I eat. Converse: ________________________________
Conditional: I say what I mean. Converse: ________________________________
