Logic and Reasoning (CH 2 review)

If an angle is 40⁰, then it is acute.

∠A is 40⁰.

Using the Law of Detachment, what is the logical statement to conclude?

• ∠A is complementary to ∠B

• ∠A is acute.

• ∠A is obtuse.

• ∠A is 40⁰

What is a counterexample?

• A generalism that cannot be applied to a specific case

• A specific case that help to prove a conjecture

• A general case that is supported by specific examples

• A specific case for which a conjecture is false

What phrase does a biconditional statement use?

• if, then

• if, when

• if and only if

• then, if

What is the biconditional that matches the statement: "A right angle is an angle with 90 degrees."

• If an angle has 90 degrees, then it is a right angle.
• If an angle is a right angle, then it has 90 degrees.
• An angle is a right angle if and only if it has 90 degrees.
• None of the above
