Download this project! Project Notes
Das ist nicht nützlich aber ein bisschen verblüffend:
Verbindet man vier Punkte zu einem Viereck (die Punkte werden in der Reihenfolge A, B, C, D und A verbunden) und verbindet dann die Seitenmittelpunkte wieder zu einem Viereck, so ist das entstehende Viereck ein Parallelogramm. Probier' es aus durch Verschieben der Punkte.
Not useful but nice:
One can connect the centers of edges of any quadrangle to a parallelogram, try by moving points!

Idea from "Zahlen, Spiralen und magische Quadrate" of Kirsten Dahl/Sven Nordqvist

Und erst jetzt Java installiert :DDD
Hab ein neues Netbook :D
Viel Spaß damit :)
Das ist cool! :D
Awesome! I proved the theory wrong! I made a square and a line!
Kidding!
i made a 1s1s version of this : (link to project) download!
Wow, you managed it with only one sprite and one script, that's cool.
(view all replies)What launguage where the broadcasts in? Because i downloaded it. but it rocks!
It's German, because I'm from Germany ;-)
very cool. so impresive that we get a parrallelogram all the time.
Thank you. Yes, it's amazing, I tried other polygons (different vertrices) but can't observe something simular. By the way GeoGebra is a great tool for geometric experiments, we use this at school.
(view all replies)I made a remix (link to project)
Very interesting project!
Thank you.
Here is an article in English that talks about this http://en.wikipedia.org/wiki/Varignon%27s_theorem
I read the article in wikipedia and i made a remix. I used a "primitive" method (link to project)
Thank you for that interesting link, I didn't know this before not either that the area of the parallelogramm was half the area of the quadrangle for convex or reentrant quadrangles.
(view all replies)That's fascinating! I never realized that the connected centers of any quadrangle form a parallelogram. Unexpected and delightful. Your project is a great visualization aid :)
Thank you, I was also amazed when I found this in a book.
Cool! Kann mir auch vorstellen, wie schwer es ist, so was zu machen :P Also, GUTE ARBEIT!
OO. Lemme test this...I learned this from a book... Ja means yes right...?
Vielen Dank, fairerweise muss ich aber zugeben, dass es nicht schwer war und so ist doch angenehmer, als wenn man mit Papier, Bleistift, Zirkel und Lineal hantiert.
(view all replies)This ought to be useful for something. I just don't know yet what it is.
Please tell me please if you figure out...
Cool! But what's the Scratch Cat doing in the scripts?
Nothing, I was not sure if it should say something therefore it's not deleted (and perhaps still waiting for it's appearence).
cool!!
Thanks
