  6. 2.1 Inductive Reasoning continued… • Making an observation to come up with a rule is called inductive reasoning. • The rule you came up with is called a conjecture. Exercise 1 from pg 98. Caveperson Stony Grok, picks up a rock, drops it and notices it sinks to the bottom of the lake. He picks up a second rock, drops it and notices it also sinks . He does this five more times and conjectures “Ura nok seblu”, which translates to: _______________. What counter example would Stony Grok need to disprove his conjecture?

  7. Testing a Conjecture • Now use inductive reasoning to come up with examples to test the following conjectures. Determine if it is a true or false conjecture, if it is false show the counterexample. 1. The square of a number is larger than the number. • Every multiple of 11 is a palindrome. 3. The difference between two consecutive numbers square numbers, is an odd number.

  8. Explanation of Copying Conjectures • In the conjecture section of your math binder you should will write C-1 all the way to C-4, which includes C-3a to C-3d, including Slope formula on page 135. 2) Copy the label C-1 Name and words after. Leave plenty of room to fill in the blank written in the proof. 3) As we encounter the different conjectures in each of the section, we will be filling them in with the correct information. 4)You will keep your conjectures in your binder all year because we will be building on these rules.

  9. Directions for Ch. 1 Test • ONLY write on the Answer sheet • DO NOT write on the test. • On your answer sheet next to your name write FORM A or FORM B • Read directions carefully. • When sketching, remember to mark the appropriate congruent parts. Mark right angles appropriately. • Check your work before turning in the test. • When you finish copy all the conjectures in Ch. 2. They are in the yellow box. • Example:C-1Linear Pair Conjecture: If two angles for a linear • pair, then_________________________.
