Question

1. choose the correct answer.

an indirect proof is an argument that begins with the assumption that a conclusion is false, then uses logical reasoning to show that the assumption leads to a ____

hypothesis

statement

contradiction

relationship

Explanation:

In an indirect proof (also known as proof by contradiction), we assume the conclusion is false. Then, through logical reasoning, we show this assumption leads to a contradiction (a situation where two statements are mutually exclusive or opposed). A hypothesis is a starting assumption, a statement is a general assertion, and a relationship is a connection between elements—none of these fit the purpose of indirect proof as well as contradiction.

Answer:

C. contradiction
