I'm saving this for the quadrilaterals unit. Although, I do think we define "sides" to be "straight lines" which has its own problems as an undefined term. Still I like this.

Four *internal* right angles would be sufficient.

How do you know which side is the internal one?

You have to keep the picture indoors at all times, otherwise it stops being a square.
