[Math] Dynamic Geometry Software for Straight-edge and Compass Constructions

educationeuclidean-geometrygeometrylearningmath-software

Geogebra is a very good dynamic geometry software. It has so many default tools, e.g. parallel line, angle bisector, tangent to the circle, inscribed and circumscribed circles, etc. But I want the tools be limited just to the straight-edge and compass, and then construct every other tool from the scratch and make new tools ("macro"s).

I can customize Geogebra toolbar, but for some reasons it may be better to use a software which its default tools are just straight-edge and compass, and the user can save macros he makes. Does such a software exist?

Thanks.

I can describe how I will do it with Dr. Geo, a free interactive geometry software I am developing.

  1. From the menu Edit>Customise interface, you select the tools you want: select and move, point, circle, segment and macro tools,

Select only the tools you want

  1. Then you save your empty sketch under the name Minimimal for example,
  2. Next time you load the Minimal sketch its comes with your customized UI, including the tools to register and play macro-construction.

I use this feature to limit the tools used for primary school activities.
