Answer 1

A. False. It has reflectional symmetry. We can reflect the figure over the center vertical line as one example. There are two other lines of reflectional symmetry.

B. True. It has rotational symmetry of 120 degrees. This allows us to rotate the figure 3 times to have it match up with itself. Each angle is between 0 and 360. 

C. False. If you rotate the figure 60 degrees, then it won't look like its original image. You'll need to rotate another 60 degrees to have it line up with itself.

D. False. There are three lines of symmetry.
