How to fold it ??

I just came across a book named "HOW TO FOLD IT" by Joseph O'Rourke.
And I find it very interesting and there is a problem which states:
Fold a square paper such that you can cut an equilateral triangle with one cut with a scissor.

For example :
Cutting a square with one cut:
Fold it from diagonal like this
Fold it from another diagonal again
Then cut straight and you will get a square



Observed the example. Now try to do with a equilateral triangle in a square

  1. 1st fold the paper to half.. then fold it along the line joining the centroid and one of the vertices. you will get your cut-line.
