I am a fan of geometry. Mostly because of aiding my daughter (junior high school) to better understand geometry questions?! First I started with AutoCAD and draw the drawings of her problems. Drawing shapes precisely, helps a lot to solve the problem. Later I find out that it is hard for her use ACAD. Then I searched the Internet and find out that there are many software specially designed for this purpose. I choose a one-month free one, Cabri II Plus (http://www.cabri.com). It is simple, easy to use, but I figured out that it is not easy to draw with measurement (or at least I couldn't find) and it is a minus for that. You can see a screen shot in the attached photo. Now I have shift back to acad. In order to make it usable for my daughter, I want to define some macros, assign icons for them for drawing a triangle, median, angle bisector, ortholine, bisecting ortholine and many other things. For myself it is much easier to use ACAD for this purpose but It is not built for this purpose but I think as far as I know and satisfies me, there is no problem. On the other hand, other software are not this much accurate and takes time for me to master. But I think ACAD is not proper for school students. I think the solution lies on the magic of Macros and LISP routines. I am wondering how many college students uses ACAD for solving their geometry homework? Is there any site to give some addins or library of LISP codes for geometric drawings? I will be glad to hear your experience of using other software for geometric drawing purposes.
