There are several resources available online for a proof of the Four Vertex Theorem. One possible source is the MathWorld website, which offers a detailed explanation and proof of the theorem using the concept of convex polygons. Another option is the Wolfram Demonstrations Project, which includes interactive demonstrations of the theorem and its proof. Additionally, many math forums and communities such as Math Stack Exchange and Quora have discussions and explanations of the theorem with references to various proofs. It is always recommended to consult multiple sources and verify the validity of the proof before accepting it.
