In this session, you will use puzzles and a classification game to explore polygons. You will play with the definitions of various polygons to begin to internalize their meaning. You will also begin to look at mathematical definitions more formally and explore how a term can have different, but equivalent, definitions.

Part A:	Hidden Polygons
Part B:	Classifying Polygons
Part C:	Definitions and Proof
