推荐理由：《Pythagorea》是一款适用于苹果系统的教育类软件APP。Study geometry while playing on squared paper.《Pythagorea》大小35.84 MB，在本站深受9363位玩家喜爱和下载。要找等，赶紧下载到手机吧。
Construct and explore different geometric objects: squares, parallelograms, perpendiculars, angle bisectors, tangents, and others. You do not need any complex instruments, even a compass; just connect points with straight lines. It looks very easy and the first levels can be solved even by children who never study geometry. But soon you will find that the same problems become much more complicated while the object position varies. The last levels require a deep thinking, intuition, and comprehension. Though, they still can be solved with just a few lines.

***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.
***The tree***
The Pythagoras tree is a fractal constructed from squares and right-angled triangles. Your Pythagoras tree grows up with each solved problem. Each tree is unique: no other tree has the same form and colors. And after all levels are completed you will see its blossom. Everything depends on you. Good luck!
