This traditional text acquaints students with the fundamental tools of geometry in an interesting way. Students are impressed with the necessity of a formal proof before being plunged into demonstrative geometry. Many proofs are done for the students to train them in the thinking process. Students are taught to think naturally, logically. and systematically through a well-written text and through abundant exercises. Students enjoy the many "extras," which include the mathematical information on several famous buildings, biographies of great mathematicians, and geometry in the world around us.
