*** About ***
XSection is an introduction to solid geometry. It teaches you how to perceive
2D representation of polyhedrons, lines, and planes from 3D Euclidean space.
No calculations, a bit of theory, and a lot of practice.

*** Is this game for you? ***
XSection follows Euclidea/Pythagorea series of geometric games.
With all these apps you can become a real Geometry Guru.

*** All definitions at your fingertips ***
If you forgot a definition, you can instantly find it in the app’s glossary.
To find the definition of any term that is used in conditions of a problem,
just tap on the Question (“?”) button in a problem statement.

*** Main topics ***
> Prisms, cubes, parallelepipeds, and cuboids
> Pyramids and tetrahedrons
> Diagonals of polyhedrons
> Cross sections
> Diagonal sections
> Parallel and central projections
> Method of traces
> Method of inner projection
