What We Did Today:
Students reviewed A and completed 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 are available by clicking here.
Focus Question:
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?
Vocabulary Discussed:
Homework:
None.
