"Award-winning teacher brings excitement to the study of geometry. Jim Noggle has taught mathematics since 1970, receiving many awards for his teaching. He brings his love of the subject to the lessons and infuses them with excitement in the 30-volume set Geometry: The Complete Course." - AV Guide. 3 Stars. "Terms are defined upon initial use; new concepts are presented in a logical, consistent manner; and Noggle emphasizes the relationships between the real, three-dimensional world and the conceptual two-dimensional representations in geometry, as well as the connections between geometric principles. It's a thorough and effective presentation. Recommended." - Video Librarian.
