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.

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.
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.
True. In an indirect proof, also known as proof by contradiction, you assume that the opposite of what you want to prove is true. Then, you show that this assumption leads to a contradiction, thereby demonstrating that the original statement must be true. This method effectively highlights the validity of the claim by eliminating the possibility of its inverse being true.

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.
