I Made Me Do It

or Dave Made Dave Do It

or @calcdave and @dcox21 are pretty much the same person so this is really a post about a guy talking about himself to himself (or would that be to himself about himself?).


So apparently Dave was eaves dropping on one of my conversations (the nerve of some people) and started asking some interesting questions. I particularly liked the triangle image and couldn't help myself especially since Jason encouraged me via GoogleChat last night (or was it GoogleTalk?) to keep doing this GeoGebra stuff.

Oh, and Jason and I live in California (which makes us pretty much the same person too, except that he lives in the Bay Area and I live in the Central Valley so we are the same person kinda like Massachusetts and Texas are the same state in that they are both part of the contiguous United States) and he lives, like right next door to Dan who's been to Canada.

So I guess y'all have to thank Canada for this applet, eh.

This is a Java Applet created using GeoGebra from - it looks like you don't have Java installed, please go to

Canada thanks you Dave. Canada also thinks maybe we need to work on your usage of the word "eh." Maybe our new mayor will tutor you?

Thanks for the mention. Yeah, that "triangle" image is one of my favorite teasers for class. It goes along with the slope concept, too. I also think the phrase "from where comes this hole" is hilarious, but I can't pinpoint why.

Very cool.

The kids and I just figured it out. If other readers are stuck like I was, here's a little one-word hint: dint.
