Geometry 2.1 – Use Inductive Reasoning Vocabulary: Inductive Reasoning: Conjecture: Counterexample: 1. Describe how to sketch the fourth figure in the pattern. Then sketch the fourth figure. 2. Describe the pattern in the numbers –1, –4, –16, –64,….Write the next three numbers in the pattern. 3. Describe the pattern in the numbers 1, 2.5, 4, 5.5,… and write the next three numbers in the pattern. 4. Given five noncollinear points, make a conjecture about the number of ways to connect different pairs of the points. 5. Numbers such as 1, 3, and 5 are called consecutive odd numbers. Make and test a conjecture about the sum of any three consecutive odd numbers. 6. Numbers such as 3, 4, and 5 are called consecutive numbers. Make and test a conjecture about the sum of any three consecutive numbers. 7. Make and test a conjecture about the sign of the product of any four negative numbers. - To show that a conjecture is true, you must show that it is true for _______ cases. - To show that a conjecture is false, you must find ___________________________. - A __________________________ is a specific case for which the conjecture is false. 8. A student makes the following conjecture about the difference of two numbers. Find a counterexample to disprove the student’s conjecture. Conjecture: The difference of any two numbers is always smaller than the larger number. 9. Find a counterexample to disprove the conjecture. Conjecture: Supplementary angles are always adjacent. 10. The scatter plot shows the average salary of players in the NFL since 1999. Make a conjecture based on the graph.
