a. Is it possible for a shape to have both reflectional and rotational symmetry? If so, provide an example with a line of symmetry for reflectional rotation and the minimum degree of rotation for rotational symmetry. If not, explain why.

Yes. For example, the shape I will use is the circle.

No matter how you rotate the circle, it will always look the same. If you reflect the circle over any drawen line in which it passes through the middle, the two halves created would be congruent.
