[Geometry] Draw a square

[rabbit]

Yeah.  Exactly.  I placed the marking tip down first and then put the anchor pin down.  I've done stuff like that before...

Yes, but you have to place it on a point. You can't just plop it down anywhere and assume that it will help you draw a square.

[Chavo]

Yea, but he explained how it was a valid assumption.  Would you still find his answer as bogus if he had actually used the center hole of a compass instead of using the center of the circle that the program found?

[Camel]

You didn't explain how you found the origin of the circles on the left and right sides.

Hint: the only way you can find those points requires having already found the entire square, which is why I'm not going to re-read what you wrote.

I got bored at work today, so I drew out the solution in mspaint. Spoiler.

Who wants to take on the pentagon?

Wrong

There's a hole there where the compass needle poked into the paper.

A strait line from one side of the circle to the other through its center is easy to do.  Doing it 4 times is easy.  The only thing that's a little tricky is making a square on the first try (hence an eraser).  Stop trying to say what I did was impossible because you didn't think of so simple an answer in your hours of toiling.

[Camel]

For the third time I'll say it: you did not explain how you found the center of the left and right circles. If you didn't break the rules, then your original explanation doesn't match what you did. Don't take it so personally.

In any event, the goal is to draw a square from two given adjacent vertecies, which your approach doesn't use.

[Ender]

Meh, the pentagon looks like a fun problem but I have 39 theorems to prove by Thursday (assigned today). Maybe I'll try it later.

EDIT: I checked out the sheet and it's not 39 theorems, the numbering includes exercises and definitions. Still, I have a lot of work to do, so I probably won't be able to get around to doing these problems anytime soon.

You seriously are retarded.  I DID say how I found the center of the other circles.  God damn.

[Camel]

I just re-read it, and I still don't see it.

Maybe you could re-write your explanation so it's possible to understand.

[Sidoh]

rabbit, calm down man.  Even if you are right, there's a more rational way to deal with it.

[rabbit]

After that I drew another circle [...] starting with a point on the intersect of the first line and the first circle.

I placed the marking tip down first and then put the anchor pin down.

That should have been clear enough

I personally don't understand your solution and haven't been able to replicate it on paper. Can you maybe give a step-by-step way of doing it? That should help everybody.

[Ender]

I don't understand your answer either I'm not saying I think you're wrong, I'm just saying I don't understand it.

I started with the bottom, and drew a line horizontally through the center.  After that I drew another circle without changing my comp--radius box on the right, same on the left, starting with a point on the intersect of the first line and the first circle.  Then I drew two vertical lines (one in each side circle) same as the bottom one, and connected the top.  The fourth circle is completely unnecessary, but I didn't realize that until after I'd merged down my layers, so eh.

Let's start out with this:

"...After that I drew another circle without changing my comp"

How can you draw another circle without changing the position of the compass? A compass at a fixed position with a fixed radius can only draw one circle. Just wondering, when you say compass, you mean the apparatus with two hinged legs attached to each other at an end, shown here, http://acsweb.fmarion.edu/math/coursedescriptions/euclidpicture320x240.jpg, right?

Also, there are no labels for any lines, intersections, origins/circles, etc., which makes it hard to understand =(
