Which one doesn’t belong?
16.2: Self Rotation
Determine all the angles of rotation that create symmetry for each shape in the applet and complete the following:[br][list][*]the name of your shape[/*][*]the definition of your shape[/*][*]drawings of each rotation that creates symmetry[/*][*]a description in words of each rotation that creates symmetry, including the center, angle, and direction of rotation[/*][*]one non-example (a description and drawing of a rotation that does [i]not[/i] result in symmetry)[/*][/list]

16.3: Parallelogram Symmetry
Clare says, "Last class I thought the parallelogram would have reflection symmetry. I tried using a diagonal as the line of symmetry but it didn’t work. So now I’m doubting that it has rotation symmetry."[br][br]Lin says, "I thought that too at first, but now I think that a parallelogram [i]does [/i]have rotation symmetry. Here, look at this."[br][br]How could Lin describe to Clare the symmetry she sees?
Sketch shapes in the applet and use ABC Text tool to write a transformation statement for each one.
