## Main Question or Discussion Point

Hey there

I do study a textbook at School called Plane Geometry, it is about 3d dimensional figures, it starts with explaining Planes, points and lines, then It starts with theories, then I have to prove something like a line perpendicular to a plane and things like that. I googled Plane Geometry, Solid Geometry and many other things but I found nothing new.

I found this website

Anybody knows where can I find anything about this interesting topic?

Thanks
