am Gutenbergplatz, 2004),[1] translated into English by Peter Hilton and Jean Pedersen, and published by the Mathematical Association of America in 2006 in their MAA Spectrum series (ISBN 978-0-88385-553-9).

[2][3] The third section provides background material and proofs for some of these points of intersection,[3] as well as extending and generalizing some of these results.

[4] However, others are new to this book,[2] and include intersections related to silver rectangles, tangent circles, the Pythagorean theorem, and the nine-point hyperbola.

[4] John Jensen writes that "the clear and uncluttered illustrations of intersection make for a rich source for geometric investigation by high school geometry students".

He adds that the book itself is a proof of the possibility of presenting geometry without detailed explanations, and of introducing students to the beauty of the subject.
