given: A triangle ABC with DE drawn parallel to BC
construction: produce EM and DN perpendicular to AD & AE respectively. Join DC & BE.
proof: I'll give it whenever i come to this site the next time

He created a proof.
triangle sum theorem
By definition, a theorem is a proven statement- until a proof is made for a statement, it is not a theorem but rather a conjecture. Whether you need to be able to reproduce the proof of a known theorem is another matter. If you trust the prover, I think you can make use of a theorem without knowing the proof. However, studying the proof can give you valuable insights into what the theorem really means and how it might be used. Also, reading proofs made by other people can help you prove you own theorems and write them up coherently.

thyales theorem
No. A corollary goes a little bit further than a theorem and, while most of the proof is based on the theorem, the extra bit needs additional proof.
Theory_of_BPT_theorem
When a postulate has been proven it becomes a theorem.
Theorems is what is proven with the geometric proof.
a theorem that follows directly from another theorem or postulate, with little of no proof

theorem always needs proof

"thales" has given this bpt theorem.
