Question

it has no reflectional symmebry it has no rotational symmetry it has reflectional symmetry with six lines of symmetry it has rotational symmetry with an angle of rotation of 30°

Answer 1

Lets draw a picture:

Then, we can see that our figure has a rotational symmetry with an angle of rotation of 30 degrees because if we rotate the figure 30 degrees the figure coincides with itself.
