Revision Of Chapter 11

Inductive reasoning uses examples to observe the pattern

• true
• false

what's the next item: 10,20,30…..

• 50
• 60
• 30
• 40

In the shown Pattern,what is the next item?

• down left

• Middle Up

• Middle Down

What are the missing numbers in red and green baloons?

• Red: 4 and Green: 8

• Red:8 and Green: 4

• Both are 8

• Both are 6

What do we call the conjecture based on numbers?

• Geometric
• Algebraic
• both of them

In inductive reasoning, we need one counterexample to prove a conjecture is false

• true
• false

Vertical angles have the same meaurements

• Never

• Always

• Sometimes

Congruent means equal in measurements

• true
• false

A statement could be always true

• false
• true

What do we mean by negation of a statement?

• Opposite of meaning (NOT)
• Opposite of the truth value
• Both of them
• None of them
