A circle thusly divided

has 12 inside corners, no more, no less,
and they each measure 90 degrees. They
measure so because the center 4 divide a
circle of 360 degrees into 4, each of which
is 90, and the outside 8 are subtended by
the circle into 4 perpendicular intersections
each of which divides 180 degrees by two,
such that the 4 pie-shaped sections each
comprise one closed complex polygon with
3 simple angles and one curved side, the
curve of which stands in place of the 4th
interior angle, and 360 divided by these 4
angles is 90 degrees each.

Witchcraft Neil... How many times? " :cussing:"  :heretic:  :farmer:

 

Comprende vous?

Correction: "Comprenez-vous?"   And if you wish to be informal use "Comprends-tu?"
DZ, je prie de vous, apprend le français!
"Mort Par Rire" ou le "lol" de France.

As an aside since we're already there, I thought that the use of "tu" without proper cause was deemed overly familiar, awkward, rude, and potentially an  invite to getting either a right proper stabbing or possibly the number of a burly truck driver, no?

Yes, but I think we've all gotten to know eachother pretty well here in "The Ghetto", so being such good friends we should all be able to affectionately use "Tu". Due to some posts one would think one knows a lot about another and vice-versa, so we should be able to be informal at this point! :)
Plus, it's fine for people who are the same age to use it also, and for adults towards those who are younger. Some even find it strange when older folks refer to them as "vous", of couse that may vary according to region.

You must have missed the part where there are no corners on a circle. Even on your pie picture there are 12 corners that I count.

.
You count correctly. That's because you're not deceived by the flat-tard devil. 
.

I did think it was rather odd when he showed his pie picture with 12 corners and tried to convince me that it was only 4 corners. For a person who trusts solely in his own perception of things, he has a hard time perceiving something pretty obvious. Is it a circle or does it have 4 sides?

This is how he tried to show that if you interpret Scripture like they do, there isn't a contradiction. Yet there obviously is if you think yourself wiser than the Holy Ghost.
That picture is funny.

Flat-earthers have a lot of trouble with geometry. They don't know how to process information about circles or portions of circles. They can only think in terms of straight lines, and so a piece of pie, for example, is only comprehensible to a flat-earther on the two cut sides of the pie piece, the sides established by the passing through of a knife. The outside curved edge is to them not an "edge" at all but a complete mystery which they choose not to to think abut, so they don't think of it as one edge of the piece of pie.
.
They consequently have nothing but utter contempt for anything shaped as a spheroid, such as an orange or an egg or beach ball or a balloon. Ask them to draw a picture of what it would look like to stand on the surface of Jupiter and look out at the horizon. They will immediately proceed to describe Jupiter as a small spot on the "firmament" and much smaller than their "flat" earth. Coming to grips with an enormous planet hundreds of times bigger than the earth is for them an impossibility, like asking an ant to solve for x in an algebraic equation.
.
In order to justify their myopic world-view they choose to think of earth as the largest entity in the universe, beyond which is some kind of physical "heaven," the description upon which none of them can agree. Furthermore, any rudimentary exercise used to test their silly notions they will always refuse to participate in in order to protect their myopic world-view. Consequently their myopic world-view becomes for them a "safe space" to where they retreat in fear of facing the stark reality that is everywhere around them. 
.
Reality is for them in their mind, and they don't care whether anything of reality exists independently of what they think.
.
They take this fearful escape from reality into their interpretation of Scripture where they only see what they want to see, and even endeavor to search all of Scripture looking for ways to superimpose their own flat-tardism into what they find.

"Check your flat privilege!"  

I don't always agree with you, but you're funny!
