A square is a regular polygon* with 4 sides.
*Regular Polygon A polygon which is both equiangular and equilateral (i.e. having all sides the same length and all interior angles the same).
Note that this doesn’t preclude the existence of a square with curved sides if projected upon a sphere. But when discussing common geometry the assumption is that we are working within a single plane. If you wish to work in non-planar geometry, that must be explicitly called out in the diagram.
a square is a polygon, and this is not
If you think that is confusing, this will blow your mind!
Here is the definition of polygon when I googled it, “a plane figure with at least three straight sides and angles, and typically five or more.”
That has at least 3 straight sides. It doesn’t state they all need to be straight.
I am sorry, but I don’t see the third straight side.
You gotta squint a little
