When you miss one important constraint in your CAD project.

Wouldn't the angles need to be interior?

Kinda forgot the sides being parallel part. Like missing a step in assembling IKEA furniture, its not gonna turn out right.

Anarchy geometry

Easy there Diogenes.

A square has all right angles inside the structure. This thing has two inside and two outside.

This has an infinite number of sides

This is what AI would give you after countless tries strating with a triangle and having gone up the Pentagon and down to two pairs of unconnected parallel lines.....but what if all equally sized lines were connected? Bam! This

270°≠90°

You could say a regular square has 4 270° exterior angles

A square? A square?! Wake up sheeple! That things not even a rombus! Don't you see the lies? Look at the lines! Look! Not all rhombuses are squares, but all squares are rhombuses! All squares are rhombuses and look at this thing they try to call a square. Where are the parallel lines? There's got to be parallel lines, don't you see, or then it's not a rombus and all squares are rhombuses. Don't forget that, don't let them take that fact from you and perpetuate their geometric lies. Does no one even remember what a rombus is? This is, this is basic geometry here that you should have learned in middle school or elementary school, but then you just forget it, and let people trick you with these misleading definitions and fancy diagrams but you have to remember that a Square. Is. A. Rombus.

Poor Pac-Man does not look quite okay... :-(

thinking outside the square

Now make a square out of squiggly yarn

String theorists claim this is the true shape of spacetime!

This is a square in polar coordinates

Take that, Euclid!

Squircle

It's Pac-Man with a megaphone!

HOW ELMO, HOW?!?

Is a corner with an angle of 180 degrees a corner? If yes, then all shapes have infinite corners and infinite edges.
