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."
lin says, "i thought that too at first, but now
i think that a parallelogram does have
rotation symmetry. here, look at this."
how could lin describe to clare
the symmetry she sees?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
