Is Blender appropriate for learning Stereometry (a subject in mathematics)? In some countries, senior high school students are still taught about Sterometry in which we are asked to draw a cross section between a solid and a plane, for example, as follows.

Shortly speaking, is Blender appropriate to use here? I am relatively new to Blender and I have not found the tools to 


attach mathematics symbols such as omega, theta, etc.
create points that are geometrically constrained such as AB:AC= 2:3, etc.
find intersecting points, etc
Looking at the image you attached I'd say it's, but to an extent. I mean you can model in B3D the solid shown and make it transparent. Use Shear for the cross-section, render it. Still, for all those lines an external image editor is the fastest way.
