Many people think there is only one "right" way to teach geometry. For two millennia, the "right" way was Euclid's way, and it is still good in many respects. But in the 1950s the cry "Down with triangles " was heard in France and new geometry books appeared, packed with linear algebra but with no diagrams. Was this the new "right" way, or was the "right" way something else again, perhaps transfor ...Whole Description

Many people think there is only one "right" way to teach geometry. For two millennia, the "right" way was Euclid's way, and it is still good in many respects. But in the 1950s the cry "Down with triangles " was heard in France and new geometry books appeared, packed with linear algebra but with no diagrams. Was this the new "right" way, or was the "right" way something else again, perhaps transformation groups? In this book, I wish to show that geometry can be developed in four fundamentally different ways, and that all should be used if the subject is to be shown in all its splendor. Euclid-style construction and axiomatics seem the best way to start, but linear algebra smooths the later stages by replacing some tortuous arguments by simple calculations. And how can one avoid projective geometry? It not only explains why objects look the way they do; it also explains why geometry is

About Restorio.eu
We give things a new story. We sell and buy books, Lego sets, board games and PC games. In the beginning, it was the wish of two enthusiasts to improve the functioning of second-hand bookstores and be beneficial to the world. Today, we create a huge community of conscious people who are looking for a sustainable shopping choice from a financial and environmental perspective. And with them, with you, we write new stories of things that would otherwise remain forgotten. We will send you the money for everything you sell to us immediately. With us, you don't wait for the books to sell. We will do what we say. We believe that even the smallest details are of great importance, so we think through every aspect of our business, from the way we buy books, through packaging materials to communication with each of you. We have designed our Restocks loyalty program of shopping credits to reward you for every support you give.
