Proofs without Words in Geometry
Nirode, Wayne
Mathematics Teacher, v110 n8 p580-586 Apr 2017
Since the 1970s, the Mathematical Association of America's (MAA) journals "Mathematics Magazine" and "College Mathematics Journal" have published "Proofs without Words" (PWWs) (Nelsen 1993). "PWWs are pictures or diagrams that help the reader see why a particular mathematical statement may be true and how one might begin to go about proving it true" (Nelsen 2000, p. i). This article explains how the author created and implemented a variation of using diagrams without words to facilitate the development of high school geometry students' reasoning and proof skills.
