* Built-in glossary with geometric terms
* Step-by-step instructions
* Easy to use

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.

Ratings and reviews

I've been playing this game for a while. After a steep learning curve, I understood how to read every detail carefully. Now I can reason out puzzles within minutes. I just finished a puzzle where I used complicated methods to successfully complete it, but then immediately realized the elegant solution that I had missed. This app is a diamond in the rough. I highly recommend it!

Good game just like their other two, but the descriptions remain somewhat cryptic. A lot of the time they just aren't terribly clear either by using terms that hadn't been described before (skew), lack of punctuation in places that would benefit from it, or just by being vague. The lack of a glossary baffles me, but the hint system is nice.

Fantastic. The Play Store listing says "has in-app purchases", and right now I'm honestly looking for where those are so I can give the developer money. (Aha, found it. Starting with chapter 8, each problem has a 4-hour delay, counting from when you finish the previous problem. Tap on the displayed countdown to be offered to bypass this and all future delays for a one-time fee of about $2.)
