True
It is true that the body of an indirect proof you must show that the assumption leads to a contradiction. In math a proof is a deductive argument for a mathematical statement.

Given a proposition X, a regular proof known facts and logical arguments to show that X must be true. For an indirect proof, you assume that the negation of X is true. You then use known facts and logical arguments to show that this leads to a contradiction. The conclusion then is that the assumption about ~X being true is false and that is equivalent to showing that X is true.
The logic indirect proof solver can be used to solve complex problems by working backwards from the desired conclusion to find a contradiction. By assuming the opposite of what you want to prove and showing that it leads to a contradiction, you can demonstrate that your original assumption must be true. This method allows you to prove statements that may be difficult to directly prove.
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.
Indirect reasoning is a method of proving a statement by showing that its negation leads to a contradiction or inconsistency. Instead of proving a statement directly, one assumes the negation of the statement and derives a contradiction to demonstrate that the original statement must be true.
