How To Solve The Hardest Easy Geometry Problem
High school geometry
Euclidean geometry is a mathematical system attributed to Alexandrian Greek mathematician Euclid , which he described in his textbook on geometry : the Elements. Euclid's method consists in assuming a small set of intuitively appealing axioms , and deducing many other propositions theorems from these. Although many of Euclid's results had been stated by earlier mathematicians,  Euclid was the first to show how these propositions could fit into a comprehensive deductive and logical system. It goes on to the solid geometry of three dimensions. Much of the Elements states results of what are now called algebra and number theory , explained in geometrical language.

This is a book on Euclidean geometry that covers the standard material in a completely new way, while also introducing a number of new topics that would be suitable as a junior-senior level undergraduate textbook.
It seems that you're in Germany. We have a dedicated site for Germany. Geometry is probably the most accessible branch of mathematics, and can provide an easy route to understanding some of the more complex ideas that mathematics can present. This book is intended to introduce readers to the major geometrical topics taught at undergraduate level, in a manner that is both accessible and rigorous. The author uses world measurement as a synonym for geometry - hence the importance of numbers, coordinates and their manipulation - and has included over exercises, with answers to most of them.
