Geometric Constructions

I have just created 17 new animations for Geometric Constructions

Comments and suggestions, please!

Re: Geometric Constructions

Niiiiiice pages!
There were a few tricks on there that I didn't know (or maybe had forgotten tongue), and the pentagon was particularly awesome. I also liked the magic pencil.
[Edit: Just realised the pencil isn't magic, it's just that the ruler-pencil and compass-pencil are different colours. Still makes things a lot clearer though.]

I think it'd be a lot better if you had a bar along the bottom, so people could go back and forward at their own pace (like in YouTube, for example). A pause button would be good too, so people could follow along.


Why did the vector cross the road?
It wanted to be normal.

Re: Geometric Constructions

Thanks Mathsy ... it took a lot of time and patience to put them together. Forward and rewind would be hard, put pause is possible I think.

I just hope I made no mistakes, as I will link to them from the main website soon.

Re: Geometric Constructions

Really nice job. Excellent!


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
