Geometric transformations of the plane (e.g. reflections, rotations, translations, and dilations) are studied in high school geometry classes. Rather than reflecting points (and
sets of points) over a given line, what happens when we “reflect” them over a given circle? (This is Pi Day, so circles should pop up.) We will dive into the strange world
of inversive geometry where points are “reflected over a circle.” This session will include some active work in pairs. If you can, bring a screen that can be viewed by two
people (e.g. a notebook computer or tablet).
