Last week, I wrote a post about using a hole punch to find function inverses in algebra. A few people asked on Facebook if the process would also work for geometric reflections, and it absolutely does! In this post I share an easy, hands-on method for demonstrating reflections and rotations of geometric shapes and their coordinates in the coordinate plane. The video included in the post covers reflecting over the x-axis, over the y-axis and over the line y = x. This same method will work for…
