Question

Which of the following is not an acceptable form of proof

a. two-column proof
b. indirect proof
c. conjecture proof
d. flowchart proof

Answer 1

Conjecture proof

Explanation:

In the field of mathematics, conjectures means arriving at a conclusion without complete or proper information, for which the proof or disproof have to be found yet. It is a statement in mathematics that has not been proved rigorously. Conjectures come into picture when someone notices a definite pattern which can hold true for some cases but that does not confirm that these patterns also hold true for all the other cases. Thus Conjecture proof is not fully accepted.

Answer 2

I think the correct answer from the choices listed above is option B. It would be an indirect proof that is not an acceptable form of proof. This is because this type proof is not used by any problem. Hope this answers the question. Have a nice day.
