Write each statement as a conditional statement. Identify the hypothesis and conclusion. Write the converse, inverse, and contrapositive of the original conditional statement. A man that is six feet tall can wrestle a crocodile.
Original: If a man is six feet tall, then he can wrestle a crocodile. Hypothesis: A man is six feet tall Conclusion: He can wrestle a crocodile Converse: If a man can wrestle a crocodile, then he is six feet tall. Inverse: If a man is not six feet tall, then he cannot wrestle a crocodile. Contrapositive: If a man cannot wrestle a crocodile, then he is not six feet tall.
Write each statement as a conditional statement. Identify the hypothesis and conclusion. Write the converse, inverse, and contrapositive of the original conditional statement. An acute angle has a measure less than 90 degrees.
Original: If an angle is acute, then it's measure is less than 90 degrees. Hypothesis: An angle is acute Conclusion: It's measure is less than 90 degrees Converse: If an angle's measure is less than 90 degrees, then it is acute. Inverse: If an angle is not acute, then it's measure is not less than 90 degrees. Contrapositive: If an angle's measure is not less than 90 degrees, then it is not acute.
