Activity Overview

Students explore a special subset of the transformations of a square called the symmetry group.

Key Steps

  • Image

    Students reflect and rotate a square using the features of the Graphs & Geometry application. The square is imprinted with the letter F to show students how the orientation of the square changes.

    Next, students delve deeper into the mathematics behind these transformations by creating a matrix of vertices for the original gray square and the transformer matrix.

    Finally, students use similar tools to explore a different symmetry group.
