Find each of the following. 5. m PQT if m PQR 25 and m RQT. 6. m PQR if m PQR (0x 7), m RQT 5x, and m PQT (4x 6). 7. m PQR if QT bisects PQR, m RQT (0x 3), and m PQT (6x ). 8. Marc doesn t think that the angle of the front seat in his mom s car is very cool, so he tilts the seat back. m ZWY 95 and m YWX 30. Find m ZWX. Find the next item in each pattern. 9. 2, 4, 6, 8, Z, Y, X, fall, winter, spring, Complete the conjecture. Give at least 3 examples to support your conjecture. The sum of two odd numbers is. 23. Using the conditional below: Negate the conditional statement, then write the converse and the inverse. For every statement, even the original conditional statement determine if it is true or false. If it s false, write the counterexample. If two rays have the same endpoint, then they are opposite rays.

For every statement, even the original conditional statement determine if it is true or false. If it s false, write the counterexample. If an animal is a bird, then it has two eyes. 25. Show that the conditional is false by finding a counterexample. When the letters i and e appear next to each other in a word, the letter i always comes before e. 26. Identify the hypothesis and conclusion of the statement: If it is raining, then there are clouds in the sky. 27. Write a conditional statement from: A giraffe has four legs. 28. There is a myth that a duck s quack does not echo. A group of scientists observed a duck in a special room, and they found that the quack does echo. Therefore, the myth is false. Is the conclusion a result of inductive or deductive reasoning? 29. Given: If you are eating a banana, then you are eating fruit. If you are eating fruit, then you are eating food. Tommy is eating a banana. What can you conclude? 30. Given: If you are a student at Strong Rock, then you went to chapel on Tuesday. If went to chapel on Tuesday, then you went to your small group.\ Annie goes to Strong Rock.
