Answer:
A. Both rotational and reflectional.
Step-by-step explanation:
We have been given an image of a regular polygon. We are asked to determine type(s) of symmetry for our given polygon.
Upon looking at our given polygon, we can see that it is a pentagon.
We know that a regular pentagon has five equal sides and five lines of symmetry.
We can see that each line of symmetry divides pentagon into two mirror images, therefore, our given pentagon has reflectional symmetry.
We know that the regular polygon has a rotational symmetry. We can find rotational symmetry of a regular polygon by multiplying 360 degrees by number of sides.
Therefore, a regular pentagon has rotational symmetry.
