When you say "ruler", do you mean a marked straightedge? There are well-known methods for doing this, so if your father has invented a new one then that is cool.

Somehow, I suspect you actually mean an unmarked straightedge, in which case your father is wrong. There is a mathematical theorem which has proven this is impossible.
