Pi and Squaring the Circle

In this video we show the viewer how to square a circle, using only a straightedge and compass,
and at the same time also show how the conversion constant for calculating the surface area of a circle is derived.

Pt 1.

This is not geometric proof. It's geometric nonsense. And in your sidebar info, "we" should be singular.

There is no such thing as a 4-8-9 right triangle. Everything else is obfuscation, and quite irrelevant, given that you are using a triangle in your proof which cannot exist. You did NOT show the Pythagorean theorem. Adding 1 to each term is pure BS. You did that so you could simply *change* 64 to 65!! And where did you get 8 for BC???

Cont'd.

i work in a warehouse driving a fork lift truck and even i know this is complete bollocks!

You can prove that the ratio between the circle's circumference and its radius isn't 3:1 merely by empirical testing. 1 counterexample is enough. I can't believe I'm bothering to say this, considering your brain is infected with religion.

@Astrobrant2  what he said! >:)

ahhhhhhhhhhh WRONG!!!!!!!!! FAIL!!!!!!!! Take this crap down

HAHA what a stupid nonsence this is!! Nothing is squared. You can easy see that the area of​the circle is 63,61725124 and the area of​the square is 64.

All the rest is not true too. The Pythagorean theorem states a^2 + b^2 = c^2 and not a^2 +1 + b^2 +1 = c^2 + 1 so as you can see you have add 1 to the right side and 2 to the left site with would be the same as you say 2+3 = 5 so 2+1 + 3+1 = 5 +1 . Now 3 + 4 is clearly not equal to 6 .

A religious idiot ? Plz stop

Incorrect. Your version require degree and angles. Thus more than a straightedge is required. A ruler, while it is a straight edge a straightedge is not always a ruler.

This is what it should look like.

bull shit.....

This is horse shit.

This is what happens when people smoke too much weed and then they decide to "write history".

Pt 3.

But the simplest disproof of this nonsense is yet to come:

The radius is 4.5. So the area of the circle is (4.5)^2 times pi. That's 63.6172.... NOT 64.

As squaring "proofs" go, this one is pretty dumb. I've seen much better, but they're wrong, too.

Stop mis-informing people. Do the right thing and take this video down, since it is pure BS and likely to confuse beginning geometry students.
