Mathematics competition is an important platform to improve students' thinking and ability, so the questions of mathematics competition are more difficult and more comprehensive than ordinary questions. The examination of proof by contradiction in junior high school mathematics competitions can improve students' thinking and ability in many aspects and has an educational value that cannot be ignored. The author gives examples to explore the specific application of proof by contradiction in solving junior high school mathematics competition questions. Analyze its investigation value in the competition.
