In my opinion, one of the most exciting advances in mathematics education is the development of dynamic geometric software that allows students to manipulate constructions, perform explorations and make conjectures that they subsequently attempt to prove. This project will demonstrate, implicitly and explicitly, how such software can be used in the classroom to enhance secondary mathematics instruction. The topic I have chosen for this demonstration is the Law of Sines. I have attempted to present material ranging from the basics to problems which should be challenging for advanced students.
