Right angles can’t be on the outside of the shape, and I don’t think the two angles on the far right can possibly be 90 degrees. They might be like 89.99 degrees for a split second, but never fully 90.
Rounding is banned?
Yes. Especially when it comes to geometric shapes. Congruence must be down to the farthest decimal.
I would apply this same critique to the two outside almost right angles as well.
In this realm, zero width lines don't exist. All lines are at least the width of a Planck Length, all points have a minimum volume of the Planck Volume, etc. Practically, lines are typically much wider than these theoretical minimums, which makes finding a true straight line or right angle in nature a rarity.
Which is why geometry operates in the theoretical.
Also not a square then. The angles are infinitesimally curved, it's impossible to detect with the resolution of your iPhone, however. 
I would say, yes, if the corners are rounded, not a square. Probably some leeway with instructions being to operate under the assumption that the lines are straight.
A square is a specific type of shape: a polygon. All polygons are shapes; not all shapes are polygons.
This is not a polygon, therefore it cannot be considered a square.
All parallelograms are polygons; not all polygons are parallelagrams
Pretty sure all the sides of squares have to be straight lines.
Squares are simply equilateral rectangles and all rectangles require opposing sides to be parallel. I guess this is supposed to be some kind of "Behold, a man" analogy...
