Math/Geometry

[Geekthras (The Gizmo of Yore)]

Come here to talk about any math or geometry things that you've done or want to find out about! Recently, I made a paper truncated tetrahedron and a rhombicuboctohedron(sp?) and I'm working on a snub cube. Anyone else make that kind of thing?

I am very poor with geometric terms. I know that a right angle is ninety degrees and a circle is three-hundred and sixty degrees.

Other than that I'm pretty clueless about geometric terms.

I would love to see whatever projects you wish to share with us though.

Here's one that took me and my friend a year to solve (and we still don't know if we're right)
find the angle x

one e-cookie to who ever solves it

(BTW, guess and check doesn't work)

[Captain Awesome]

Are we finding angles? I assume we are, since your drawing would be horribly not-to-scale otherwise.

...as opposed to being just medium-ish-ly not-to-scale now.

[Blastgirl]

I don't really get it though what are you suppose to figure out?

yah, I'm just used to stuff like this being assumed. Doesn't matter, no one will get the right answer anyways

OK, this is killing me.

I took the end of course test for Geometry yesturday

Just now I realize how many things don't add up to 180 nor 260 360.

[slippy0]

heh, wanna no something weird?
you can input any number (from 0 to 130) for x, and all the angles will add up with no problem, but logically, there is only one possible angle (just believe me if you can't tell why).

The bottom traingle is semetrical, and the two on to of it are basically the same thing. Their top point (This point is part of X's angle), can only align into one spot, this dependant upon the angle of the "10" and "20"

I don't really know the equation for this, I haven't really done a lot of geometry.

more or less, yah.
As for taking geometry, I havn't taken it at all yet, I just studied off the internet ;D (though I did study with a friend in it, so I know the entire course before I do anything...)

Well, though I can't 100% say thats wrong, my work comes up otherwise (btw, my work is exessivly ugly, and I quite possible carried something wrong).
how did you get that answer, stunts?

[Geekthras (The Gizmo of Yore)]

I know that it is possible to solve, but I do not have it yet. I'll post it later. I used trig though.

I...don't quite know.

I went off the fact that the vertex at the middle of the whole drawing has a somewhat 90 degree angle on the left, so I went off of that. The problem isn't wrong, I checked the addition of the angles; but I can't say it's the only right conclusion either. This is a tought one, slippy.

You can basically put any number there, like you said. So this isn't an "x = 70" problem, more of a "x = {n,n,n,n...}" problem.

[im_an_alien]

has a somewhat 90 degree angle on the left

My geometry teacher said to "never trust thee diagram". Basically what it means is you have to look at the numbers and stuff, you can't just go on what it looks like. "not drawn to scale"

And also, I think you should add another number or two so you can only have one answer
