This lesson is based on the MTLT article, “Geometric Reflections: Why Should They Not Be Just a Flip?” by Dawn Teuscher, Shannon Dingman, Travis Olson, and Lisa Kasmer. In this lesson, students reflect points and figures to formulate a mathematical definition of reflection. Then, they identify and justify whether points and figures are reflections!
