Cool game, well made, but it's driving me nuts. I'm stuck on 3/40 - I've created the enclosing circle for "in origin circle" but game doesn't want to acknowledge it. Clearly I'm doing something wrong....
That's a lot better. I'd like to see it try to snap when dragging. I notice I can click once (compass) and click again on a point, but a click-drag to a point doesn't seem to snap to the point.
I recently bought a copy of Euclid and it's been sitting on my bookshelf, waiting for that ever-receding "when I have the time." It's like the author set out to give me the most perfect and thoughtful birthday present. :)
I went through couple levels before I realized I got more tools as I go on. Was using just intersect, segment,and compass and things were getting crowded.
I'm struggling on 17. There is no circle that intersects both A and B that is tangential to the line. That's how I interpret the instructions for that level, anyway. However, it seems there should be an infinite amount of circles that are tangential to the line that can intersect A.
Is that to mean tangential to anywhere on the line that intersects B, or B is the point at which the circle is tangential to the line that intersects B?
Looks cool! I think math needs to be taught in that kind of style, where people learn by doing it. I would be interested in having something similar to that on my site, Learneroo.com. One suggestion: start people off by walking them through easy challenge so they learn the interface.
This game is very similar to my first year of college mathematics -- studying Euclid's Elements and working through the proofs. I look forward to the game version of my sophomore year -- Apollonius' conic sections and Ptolemy's astronomy.
I'm not sure about you guys, but I'm not getting any feedback whatsoever. I've measured it with all the tools I can find, but I'm not getting any "Well done" or any link to the next level. Any thoughts?
Well, no shit. But I'm saying I constructed an equilateral triangle but the game wasn't recognizing it. After reloading the page a few times it finally started giving feedback, like thickening the line when moving over it (which wasn't happening before), letting me actually place the dot on the intersection between the two circles
Mind blown! very good idea,the controls are a bit rough,but it could be a great tool to teach geometry and trigonometry in general.I went up to level 4,do you "support" tangents?
I wonder what other mathematical axiom sets can be pretty much directly translated in a game like that. Maybe something from calculus, topology or knot theory.
Really cool game and great idea, there's some good educational potential here. I'm looking forward to exploring Euclid's proofs again in this digital format. This easily beats dilly-dallying with a real-life compass.
My high school class had hand drawn first semester, autoCAD second semester. (I happened to only be taking the second semester, because I needed another class to fill that semester, so I personally only experienced the autoCAD component)
From my comments you can see that it is in my experience, and my school was not top-rated at all. It was wrong of me to assume everyone else had the same experience.
I'm not even sure I know what a geometric proof is, so I'd say no?
Our teacher would just ask us to solve this sort of exercises with a compass and a ruler, and then he'd grade the tests by checking whether the process to reach the solution made sense (i.e.: I'm pretty sure that level 20 was one of the questions in my midterms). He would have explained the resolutions for most of them in previous lectures, but others were new to us. I can't remember if an additional written proof was required.
