XSection is a trainer of solid geometry problem solving. It teaches you how to perceive 2D representation of polyhedra, lines, and planes from 3D Euclidean space. All the problems can be solved without complex calculations. The app contains the required theory facts and explanations. If you forgot a definition, you can instantly find it in the app’s glossary.

XSection is a perfect way for students to practice before tests or exams and to improve your spatial imagination. The app will not allow you to create an impossible object: for example, to "intersect" skew lines (which is a typical error when constructing cross sections on paper).

The best way to learn to solve math problems is to solve them a lot.

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

XSection follows Euclidea - Pythagorea - Pythagorea 60° series of our geometric games. With these apps you can become a real Geometry Guru!

Starting from the 8th chapter levels are unlocked at 4-hours interval. But you can buy an IAP that removes this restriction.

Good problems but it needs more of them. I could do with another 5 or 6 sections like 11...

Omg, I kept the old phone that runs old Android version just for this game and other Geometry games from the same dev. It's so happy to see them now available for my phone. You made my day 💕❤️💕. About SectionX: It is one of the best games ever made for those who are into Geometry. Don't miss it. It's awesome.

o jogo é ótimo, mas acho que precisa de uma revisão de layout para aumentar as margens da borda do celular e para que o texto não fique atrás do notch da câmera frontal

I think the answer to the level 9.5 is wrong. please check. I absolutely loved this app except for the fact that you never respond to the reviews. it's been more than 2 years I sent you a feedback about the wrong answer to the puzzle number 9.5. but you didn't check or correct it. please do review the answer of 9.5.
