# How do I mulitply two lines togather???

## Recommended Posts

I am almost done squaring a circle, but I need to know how to multiply two lines togather. Does anyone know how to???

eh? Multiplying two vectors together? Or what?

What's "squaring a circle"?

Squaring a circle is when you have a circle with a certain area, and with nothing but a straight-edge and compass, one tries to calculate the dimensions of a square with the same area as the circle.

I have a line that is pi units in length, and I need to multiply it by a line 6 units in length in a construction, but I don't know where I can find the construction online!!! Aghh!!!

Never mind, I found out how to multiply two lines togather.

Ah, I see what you mean by multiplication now.

Is it squaring a circle or squaring a triangle that's impossible?

One of those.

You thinking of trisecting an angle?

What is "trisecting an angle"?

Dividing it into three equal angles. This is the popular one that can't be done with just a compass and straight edge.

Yeah, I can't trisect an angle!!! But, I have other ways around it...

In theory its impossible, but I got bored, so we're all going to find out, won't we?

Well, it's been proven to be impossible, so unless you want to waste a lot of time...

That's all I have! I would like to see the proof proving squaring a circle is impossible, does anyone have a link?

Lemme see where to begin.... take the circumferance of the circle. $C=D\pi$ This is very important, but I will show you why later.

And the area of the circle would be $A=r^2\pi$, that too is the area of the square, correct?

Therefore, the side of the square MUST be $r\sqrt{\pi}$, correct?

Well, remember the Circumferance? Well, Squareroot it. $\sqrt{D\pi}$, and squareroot the diameter on its own too. Now, plug it in $\sqrt{D\pi/D}=\sqrt{\pi}$ Multiply by the radius, which we began with! Is this not correct???

I'm not sure what you're trying to state there...

We began with C = Dπ...

So what?

Is this not correct???

No, because the 'answer' is transcendental.

yeah, squaring a circle is proven to be impossible. and trisecting angles is possible for some specific angles. but its impossible for a general angle.
