[telosfd]

I like your Greeks!!!!!!!!!!!

Ok i like it .

The previous method was less than illuminating to say the least. This trick is much better. Thank you for this video.

actualy if you have a ruler you only have to fold it once and then devide the length of the diameter of the circle by 2 and then you have the center

[jesper92]

... if you have paper you can just fold the circle in half twice to find the center and measure the radius

[peg2003]

So all you need really is something with a right-angle on it - like a set square? As long as its edges are longer than the diameter of the circle, you don't need to have the "right" size of paper. Or you can use another piece of paper. Is this correct? Thanks for the nice video. :)

@peg2003 That's correct you don't need to use the sheet of paper you drew the circle on. It can be anything that has a 90 degree corner.

wow that's awesome, quick and easy!

[rigimp]

does this circle have to be in the dead center of the page for this to work?

[AlexPleaseHelpDotCom]

@rigimp No the circle can be anywhere. And technically you dont even need a whole circle.

If you're using a compass and straight edge the only thing you have to have is space to draw the lines and curves.

That's quite cool. Simplicity is awesome.

This is cool, you definitely made my method look more legitimate. What program did you use to draw these figures?

[AlexPleaseHelpDotCom]

I use a program called Geogebra. It's free and awesome.
