What is a theorem? And the proof of the theorem.

Theorem – This is a statement that was proved from previously established statements. It can be said that the theorem is a consequence of the axiom
We can say that the theorem is the same problem, only more specific. To prove the theorem you need:
1) Build a clear drawing and mark everything that is needed on it;
2) Write absolutely all the values ​​that are in the “Given”
3) We remember absolutely everything that will help to come to the correct proof and construction of our thoughts (remember the necessary theorems and axioms)
4) We think over all the variants of the proof, prove (that is, solve) and get the correct answer (Proven or not)
