true
The goal of a proof by contradiction is to establish the truth of a statement by assuming the opposite is true and then demonstrating that this assumption leads to a logical contradiction. By showing that the assumption cannot hold, the original statement is validated. This technique is particularly effective in cases where direct proof is challenging. Ultimately, it reinforces the validity of the proposition by revealing inconsistencies in its negation.
False. In an indirect proof, you assume the opposite of what you intend to prove is true. This method involves showing that this assumption leads to a contradiction, thereby confirming that the original statement must be true.
Self-contradiction in logic occurs when a statement contradicts itself or leads to a logical inconsistency. One example is the statement "This statement is false." If the statement is true, then it must be false, but if it is false, then it must be true, creating a paradox. Another example is the statement "I always lie," which leads to a similar contradiction.

true
To demonstrate the validity of a statement using proof by absurdity or contradiction, we assume the opposite of the statement is true and then show that this assumption leads to a logical contradiction or absurdity. This contradiction proves that the original statement must be true.
The first step of an indirect proof is to assume that the statement you want to prove is false. This assumption leads to a logical contradiction when combined with established facts or previously proven statements. By demonstrating that this assumption leads to an impossible or contradictory conclusion, the original statement can be concluded as true. This method is commonly used in mathematical proofs to establish the validity of a theorem or proposition.
