TIL there’s only one national flag that’s the same whichever way you wave it – Switzerland. I.e it has four lines of symmetry – it reflects onto itself horizontally, vertically or through either diagonal.

  1. Learning is cool.
    We covered this in my 4th grade geography.

  2. Should go the extra step and make it a red circle with another white concentric one.

    Also, CH can’t fly an upside down flag!!

  3. That’s not true, what about Japan? C-infinite symmetry there!

  4. You discovered that the Swiss flag is a square with a cross?
