It's easy enough to fold a piece of paper in half. Just fold one end onto the other. But whenever I fold paper into thirds, I just guess where one third is and fold it there.
But there is a way to fold it into thirds exactly. Can you figure it out?
(This is a relatively easy puzzle inspired by my recent attempts at origami. In the mean time, I've been trying to figure out if there is a way to fold an exact regular pentagon. It seems that the standard way is to approximate.)
