Time to test this "Mastodon Poll" thingy ...

Is a square a special kind of rectangle?

@ColinTheMathmo very different response to your equivalent twitter version. Interesting!

@Bruce Isn't it.

Context matters.

I've been told that primary school teachers have been told to teach that a shape can be either a square *or* a rectangle but not both.

@ColinTheMathmo no do share

I'd like to know what "it depends" _on_, if anyone giving that answer would care to explain.

@ColinTheMathmo Square is a special case of a circle…

In a #Lebesgue space (p = ∞).

@ColinTheMathmo P.S. Or p = 1, but, wait, that's rhombus…

@amiloradovsky That's using a definition of "circle" that then varies as you change your metric.

Interesting stuff, but not really the question we're looking at.

It's all about the distances/metric/norm/etc.

@amiloradovsky Indeed, I know that, just not sure it's all that helpful in this context.

Useful in other contexts - I use it quite a lot in various places.

@ColinTheMathmo that's where this rabbit hole leads. 🐇

Thanks.
