Salkind\u003c\/b\u003e (Author)\u003c\/p\u003e\u003cp\u003eDesigned for high school students and teachers with an interest in mathematical problem-solving, this volume offers a wealth of nonroutine problems in geometry that stimulate students to explore unfamiliar or little-known aspects of mathematics.Included are nearly 200 problems dealing with congruence and parallelism, the Pythagorean theorem, circles, area relationships, Ptolemy and the cyclic quadrilateral, collinearity and concurrency, and many other subjects. Within each topic, the problems are arranged in approximate order of difficulty. Detailed solutions (as well as hints) are provided for all problems, and specific answers for most.Invaluable as a supplement to a basic geometry textbook, this volume offers both further explorations on specific topics and practice in developing problem-solving techniques.\u003c\/p\u003e\u003ch3\u003eAuthor Biography\u003c\/h3\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eAl Posamentier is currently Dean of the School of Education and Professor of Mathematics Education at Mercy College, New York. He is Professor Emeritus of Mathematics Education at The City College of the City University of New York, and former Dean of the School of Education, where he was for 40 years. He is the author and co-author of more than 55 mathematics books for teachers, secondary and elementary school students, and the general readership.

Posamentier: Math's Champion \u003cbr\u003e\u003c\/b\u003eDr. Alfred S. Posamentier, Professor Emeritus of Mathematics Education at New York's City College and, from 1999 to 2009, the Dean of City College's School of Education, has long been a tireless advocate for the importance of mathematics in education. He is the author or co-author of more than 40 mathematics books for teachers, students, and general readers including \u003ci\u003eThe Fascinating Fibonacci Numbers\u003c\/i\u003e (Prometheus, 2007) and \u003ci\u003eMathematical Amazements and Surprises: Fascinating Figures and Noteworthy Numbers \u003c\/i\u003e(Prometheus, 2009) \u003c\/p\u003e\u003cp\u003eHis incisive views on aspects of mathematics education may often be encountered in the Letters columns and on the op-ed pages of \u003ci\u003eThe New York Times\u003c\/i\u003e and other newspapers and periodicals. For Dover he provided, with co-author Charles T. Salkind, something very educational and also fun, two long-lived books of problems: \u003ci\u003eChallenging Problems in Geometry\u003c\/i\u003e and \u003ci\u003eChallenging Problems in Algebra, \u003c\/i\u003e both on the Dover list since 1996. \u003c\/p\u003e\u003cp\u003eWhy solve problems? Here's an excerpt from a letter Dr. Posamentier sent to \u003ci\u003eThe New York Times\u003c\/i\u003e following an article about Martin Gardner's career in 2009: \u003c\/p\u003e\u003cp\u003eTeachers shouldn't think that textbook exercises provide problem-solving experiences -- that's just drill. Genuine problem solving is what Mr. Gardner has been espousing. Genuine problem solving provides a stronger command of mathematics and exhibits its power and beauty. Something sorely lacking in our society.\u003c\/p\u003e\u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 272\u003c\/div\u003e\u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.54 x 8.47 x 5.43 IN\u003c\/div\u003e\u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e May 21, 1996\u003c\/div\u003e","brand":"Books by splitShops","offers":[{"title":"Default Title","offer_id":42176229277831,"sku":"9780486691541","price":16.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/2623\/2711\/files\/e9510828dba41f9213f9c31a0b09ee44.webp?v=1733388048","url":"https:\/\/booksby.splitshops.com\/products\/challenging-problems-in-geometry-paperback","provider":"Books by splitShops","version":"1.0","type":"link"}
