Geometry in Action

IMG_738111.JPG thumbnail158454
Students in Mrs. Palazzolo's Geometry Labs used "Miras" to explore the concept of symmetry and reflections as transformations in two dimensional geometry. The "Mira" is an optical drawing instrument. The "Mira" has an advantage over using a mirror because it allows the student to see the original at all times. The result being able to map one image over another. Students started with words and moved onto reflections on the coordinate plane.
