This is a fascinating, insightful, and easy-to-read look at some of the most amazing aspects of geometry and mathematics. Everyone knows what a triangle is, yet very few people appreciate that the common three-sided figure holds many intriguing "secrets." For instance, if a circle is inscribed in any random triangle and then three lines are drawn from the three points of tangency to the opposite vertices of the triangle, these lines will always meet at a common point - no matter the shape of the triangle! This and many more interesting geometrical properties are revealed in this entertaining and illuminating book about geometry. Requiring no more than a basic understanding of mathematics and written in clear and accessible language, "The Secrets of Triangles" gives readers an insight into some of the most enjoyable and fascinating aspects of geometry.
