Transformers (Matrices)

Activity Overview

Students explore a special subset of the transformations of a square called the symmetry group. They also find inverses of each transformation in the symmetry group. They then delve deeper into the algebra behind transformations, connecting them with matrix multiplication. Last, students extrapolate what they have learned about the symmetry group of a square to characterize the symmetry group of a triangle.
