Learn how to construct cross sections of polyhedrons. Study different techniques, train yourself, and then solve geometric puzzles. > 105 tasks: from basics to challenges > 12 subjects to explore > Step-by-step instructions > 35 geometric terms in a glossary > Night mode > Easy to use > Develops your spatial imagination *** 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 *** Questions?
