Question

An indirect proof has been successful if you reach a contradiction of a known fact.

a. True
b. False
c. Cannot tell

Answer 1

true if you really think about it start asking questions if you don't understand hope i help you good luck

Answer 2

True

Explanation:

First we must understand the difference between direct and indirect proof

A direct proof assumes that the hypothesis of a conjecture is true, and then uses a logical well defined arguments to prove that the conclusion of the conjecture is true.

An indirect proof assumes that it is not true and hence relies on a contradiction to prove , and then running into a contradiction proving that the conjecture must be true.

Thus we assume a contradiction and proceed then we get a wrong conclusion stating that our assumption is false.

Thus a) True.
