Sinopsis
Geometric Exercises in Paper-Folding introduces plane geometry through hands-on paper folding, with clear explanations and vivid diagrams.
This edition follows a careful revision by the editors, including added references and many half-tone photographs to replace the original line drawings.
This book blends classic geometry with practical folding methods. It guides readers from the fundamental square to regular polygons, conic sections, and other curves, showing how simple folds reveal deep geometric truths without heavy machinery. It emphasizes concepts like symmetry, congruence, and the visual nature of proofs, while demonstrating how algebra and trigonometry illuminate geometric ideas.- Learn to fold squares into equal parts, right triangles, and other basic shapes without instruments.
- See how folding can illustrate polygonal, circle, and conic concepts in a concrete way.
- Explore topics from the square to nonagons, decagons, and beyond, plus general principles and interesting curves.
- Appreciate the historical and educational context of paper-folding as a tool for understanding geometry.

Excerpt from T. Sundara Row's Geometric Exercises in Paper Folding
The purpose of the book is so fully set forth in the author's introduction that we need only to say that it is sure to prove of interest to every wide-awake teacher of geometry from the graded school to the college. The methods are so novel and the results so easily reached that they cannot fail to awaken enthusiasm.
Our work as editors in this revision has been confined to some slight modifications of the proofs, some additions in the way of references, and the insertion of a considerable number of half-tone reproductions of actual photographs instead of the line-drawings of the original.

Excerpt from T. Sundara Row's Geometric Exercises in Paper Folding
Our attention was first attracted to Sundara Row's Geometrical Exercises in Paper Folding by a reference in Klein's Vorlesungen über ausgewählte Fragen der Elementargeometrie. An examination of the book, obtained after many vexatious delays, convinced us of its undoubted merits and of its probable value to American teachers and students of geometry. Accordingly we sought permission of the author to bring out an edition in this country, which permission was most generously granted.

Impresión bajo demandaLibrería: Forgotten Books, London, Reino Unido
Calificación del vendedor: 5 de 5 estrellas
Paperback. Condición: New. Print on Demand. This book presents a unique approach to understanding geometry, using the familiar and accessible tool of paper folding. The author, a pioneer in this field, draws on the principles of Euclidean geometry while introducing novel methods and applications. The book guides readers through the construction of various regular polygons, from squares and equilateral triangles to pentagons, hexagons, and even nonagons. The author skillfully integrates principles of algebra and trigonometry, demonstrating how they can illuminate geometric concepts. Readers will find themselves exploring fascinating problems of ancient and modern geometry, unveiling the hidden relationships between these often separate disciplines. The book's exploration of geometric series and harmonic progressions not only provides visual representations of these fundamental mathematical concepts but also delves into intriguing historical problems, like the Delian problem of duplicating a cube. The author's detailed examination of polygons and their properties leads to a deeper understanding of the fundamental concepts of area, perimeter, and the calculation of pi. This book offers a refreshing and engaging approach to geometry, inviting readers of all ages to rediscover the beauty and elegance of this fundamental mathematical discipline.
