What We Did Today:
Students completed A and B from Problem 1.2: "In a Spin: Rotations." Students made generalizations regarding rotational symmetry. Students then constructed their own rotational figures using 120 degree and 90 degree rotations, choosing their own center point of rotation. Notes and vocabulary are available at http://norupstein.weebly.com/math-8-plus-blog
What does it mean to say that a figure has turn or rotation symmetry? How is each point related to its image under transformation by rotation?
