Pythagorea

Study geometry while playing on squared paper. > 330+ tasks: from very simple to really geometric puzzles > 25 subjects to explore > 76 geometric terms in a glossary > Easy to use > Friendly interface > Train your mind and imagination *** About *** Pythagorea is a collection of geometric puzzles of different kind that can be solved without complex constructions or calculations. All objects are drawn on a grid whose cells are squares. 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. 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. *** 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. *** Is this game for you? *** Euclidea users can take a different view of constructions, discover new methods and tricks, and check their geometric intuition. 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 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. *** 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, squares, rhombuses, rectangles and trapezoids > 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. It 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. 而在方格纸上打几何研究。 > 330+任务：从非常简单到真正的几何拼图 > 25例探索 >在词汇表76几何术语 >易于使用 >友好的操作界面 >训练你的头脑和想象力 *** 关于 *** Pythagorea是不同种类的几何难题，可以无需复杂的结构或计算来解决的集合。所有对象都绘制在网格上的细胞是正方形。很多的层次可以只用你的几何直观解决或通过寻找自然法则，规律和对称性。 *** 只是玩 *** 没有精密的仪器。您只可以构建直线和领域以及线交叉点的集合。看起来很容易的，但它足以提供有趣的问题和难以预料的挑战无限数量。 ***在您的指尖的所有定义*** 如果你忘记了一个定义，你可以立即找到它在应用程序的词汇表。要查找在问题的条件下使用的任何条款的定义，只需轻触信息（“I”）按钮。 ***这个游戏是你吗？ *** Euclidea用户可以利用建筑物的不同的看法，探索新的方法和技巧，并检查它们的几何直观。 如果你刚开始用几何您相识，游戏将帮助您了解重要思想和欧几里德几何性质。 如果你前一段时间通过几何体的过程中，游戏将更新并检查您的知识，因为它涵盖了大部分的思想和初等几何的概念是有用的。 如果你不和几何良好的条件，Pythagorea会帮助你发现这个问题的另一面。我们得到了不少用户的反应是Pythagorea和Euclidea使人们有可能看到的几何构造之美和自然，甚至爱上了几何。 不要错过你的机会与数学熟悉的儿童。 Pythagorea是使用几何和效益朋友花时间在一起的好方法。   ***主要议题*** >长度，距离和面积 >平行垂线和 >角度和三角形 >角度和垂直平分线，中位数和高度 >勾股定理 >圆和切线 >平行四边形，正方形，菱形，矩形和梯形 >对称，反射和旋转 ***为什么Pythagorea *** 萨摩斯的毕达哥拉斯是希腊哲学家和数学家。他住在公元前6世纪。其中最有名的几何事实，他的名字命名：勾股定理。它指出在一个直角三角形的斜边（直角相对的一侧）的平方的面积等于所述两个边的平方的面积的总和。在播放Pythagorea你经常会遇到直角，并依靠勾股定理比较两点之间线段的长度和距离。这就是为什么游戏是毕达哥拉斯的名字命名。
