Question

Angie did the following proof in her logic class. Which step in the indirect proof did she do incorrectly?

Prove: 12 is divisible by 6.

Step 1: Assume that 12 is not divisible by 6.
Step 2: 2 times 6 is equal to 12. 12 divided by 6 is 2.
Step 3: 12 is not divisible by 6.

Step 3

Step 2

Step 1

Steps 1 and 2

*i think the answer to this one is "step 3"

Answer 1

I believe you are correct.

Answer 2

Step 3: 12 is not divisible by 6.

After showing a contradiction of the assumption that the conclusion is not true (step 2), the third step concludes with a statement that the conclusion is indeed true. In that respect, it is a restatement of what was to be proved indirectly.

Answer 3

thanks :)
