Polygonal Linkages

Author:
Judah L Schwartz
This is a series of applets drawn from the website mathMINDhabits [sites.google.com/site/mathmindhabits] that is designed for teachers of mathematics who want to deepen their understanding of the mathematics they teach and that their students are expected to learn. All of the applets in this collection approach the exploration of polygons by considering them to be closed chains of hinged links. These applets provide teachers with a myriad of opportunities for posing open-ended problems that can be readily explored. I know that that these applets will keep me [and I hope many teachers and their students] engaged for a long time to come.
