### Abstract

Wallace-Bolyai-Gerwien Theorem states that any two simple polygons of equal area can be dissected into a finite number of congruent polygonal pieces. It is difficult for high school students and teachers to understand the proof. By using dynamic mathematics software,such as Geogebra, the authors can give the dynamic proof of the theorem so that students and teachers can understand the essential steps of the proof more easily.
