"It is an extremely well-done interactive encyclopedia of polyhedra" - Kurt Schmucker (Parallels Senior Product Manager) iCrosss allows you to build a cross-section of each available polyhedra by your defined plane. The plane can be defined by three points (taps) on polyhedron faces. The application supports such kinds of polyhedra as regular polyhedra (Platonic solids), Pyramids, Prisms, Anti-prisms and Archimedean solids and duals. Polyhedrons are displayed in 3D representation, which allows you to rotate it in any direction. Cool chalkboard drawing style and fonts were used for awesome look’n’feel. To build a cross-section you have to put three points on polyhedron faces in order to define a section plane. There is several view modes that you can use for better cross-section experience: 3D mode, Épure (3 projections mode), 3D cut mode. 3D cut mode is available only when you have already built cross-section. In this mode you can choose one of two solid pieces of initial polyhedron to continue work with. Available menu for printing and sending via e-mail of the polyhedron or its section. You can access information regarding selected solid, which includes short description, number of faces, vertices, edges, web-link for more information and useful formulas. Polyhedra are organized in simple list divided by categories. Moreover, you can put polyhedrons you like into favorites list. Favorite solids are marked by a golden star and can be rapidly accessed. A tutorial mode was designed for quick understanding. It will take you through the general application features. To display formulas custom rendering engine was developed.

Find more useful hints on Euclidea on our site: http://www.euclidea.xyz/faq. “Euclidea has been shown to help with imagination, intuition, and logic, all wonderful skills to develop.” – appPicker “Euclidea is an absolute joy to play…it’s a game that every math student should have and, in an ideal world, every adult should like.” – Non-Trivial Games ***About Euclidea*** Euclidea is a brilliantly original way to learn about, explore and have fun with Euclidian Constructions! Your task is to solve interesting challenges by building geometric constructions with a straightedge and compass. If you design the most elegantly simple solutions in the least number of moves, you’ll earn the highest scores. Solutions are scored in lines (L) and elementary Euclidean constructions (E). ***Start Simple and Get Smarter!*** Don’t worry if you aren’t a math wizard. Euclidea starts out with simple challenges that guide you through the basics. Once you master the fundamentals, you’ll move on to tougher, more mind-bending challenges such as inner/outer tangents, regular polygons, and more. There are 120 unique challenges in total, which are organized in packs for simpler navigation. ***Add Constructions to Your Interface*** When you learn certain significant constructions – such as angle bisectors, non-collapsing compass, and so on – they are automatically added to the Euclidea interface’s shortcut, which helps you save time and allows you to create clean, uncluttered drawings. ***Easily Drag, Pan & Zoom*** Euclidea-created constructions are completely dynamic. As such, you can drag to adjust angles, lines, radii and so on. You can also easily zoom and pan. This not only makes the experience more interactive, but it allows you to more deeply grasp the relationships between geometric elements, explore various possibilities, and analyze errors. ***Instant, Automatic Precision*** Don’t worry about spending time or effort trying to achieve perfect precision, because Euclidea automatically handles that task by pinning points, lines and circles to the app’s clean interface. ***Compete with Friends*** Who said that math isn’t a competitive sport? Challenge your friends to see who can come up with the most elegant solutions, and track your achievements and rankings via the Game Center. ***Additional Special Features*** > A helpful “Explore” mode that allows you to see the figure you need to construct > An inventory of tools that you create as you progress – you’ll need these to solve future challenges > Some challenges can be solved in more than one way, which means you can try a different approach and have even more fun ***Questions?

18 | Pythagorea 60° | Check how well you know the geometry by solving construction problems on a triangular grid. > 300+ tasks: from very simple to really hard > 26 subjects to explore > 70+ geometric terms in a glossary > Easy to use > Table of records in the Game Center *** About *** Pythagorea 60° is a collection of more than 300 geometric problems of different kind that can be solved without complex constructions or calculations. All objects are drawn on a grid whose cells are equilateral triangles. A lot of levels can be solved using just your geometric intuition or by finding natural laws, regularity, and symmetry. *** Just play *** There are no sophisticated instruments and moves are not counted. You can construct straight lines and segments only and set points in line intersections. It looks very easy but it is enough to provide an infinite number of interesting problems and unexpected challenges. *** Is this game for you? *** Euclidea users can take a different view of constructions, discover new methods and tricks, and check their geometric intuition. Pythagorea users who played on a square grid will not be bored. The triangular grid is full of surprises. If you have just started your acquaintance with geometry, the game will help you understand important ideas and properties of the Euclidean geometry. If you passed the course of geometry some time ago, the game will be useful to renew and check your knowledge because it covers most of ideas and notions of the elementary geometry. If you are not on good terms with geometry, Pythagorea 60° will help you to discover another side of the subject. We get a lot of user responses that Pythagorea and Euclidea made it possible to see the beauty and naturalness of geometric constructions and even fall in love with geometry. And do not miss your chance to familiarize children with mathematics. Pythagorea is an excellent way to make friends with geometry and benefit from spending time together. *** 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 Info (“i”) button. *** Main topics *** > Length, distance, and area > Parallels and perpendiculars > Angles and triangles > Angle and perpendicular bisectors, medians, and altitudes > Pythagorean Theorem > Circles and tangents > Parallelograms, trapezoids, and rhombuses > Symmetry, reflection, and rotation *** Why Pythagorea *** Pythagoras of Samos was a Greek philosopher and mathematician. He lived in 6th century BC. One of the most famous geometric facts bears his name: the Pythagorean Theorem states that in a right-angled triangle the area of the square on the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares of the other two sides. While playing Pythagorea you often meet right angles and rely on the Pythagorean Theorem to compare lengths of segments and distances between points. That is why the game is named after Pythagoras. *** Questions?
