> you must make an accurate regular pentagon and this is not trivial with ancient geometric methods

Does it need anything else besides some kind of protractor and ruler?

Making a triangle or square or even hexagon with rule and compass is fairly easy. Making a really regular pentagon also only needs rule and compass, but noticeably more knowledge with them. Try it.
