The series of workbooks, Key to Geometry, gives students an opportunity to discover the relationships of geometry through experience with the tools fundamental to the creation of geometry: the compass and straightedge. Key to Geometry is presented in a careful sequence to be followed with very little intervention by the teacher. Even the answer book is intended to be used for self-checking by the student. These are the answers and notes for Books 1-3 in the Key to Geometry Series. Format: PaperbackPublisher: Key Curriculum Press
