1. Title: There should be a clear title at the beginning of the proof question, explaining what problem to prove.
2. Known conditions: This section lists all known information or conditions.
3. Contents to be proved: This part clearly points out the results or conclusions to be proved.
4. Proof process: This is the core part of proof, which requires logical reasoning and deduction to prove the conclusion. This part often includes a series of steps, each step should clearly show the theorem or axiom used and how to deduce the conclusion from the known conditions.
5. Conclusion: After the proof process is over, the result of the proof should be clearly written.
6. Mathematics is a discipline that studies concepts such as quantity, structure, change, space and information, and belongs to a formal science. It is produced by using abstract and logical reasoning to count, calculate, measure and observe the shape and motion of objects.
