The interior angle of the regular pentagon below measures 108°, and the
pentagon has rotational symmetry Which of the following is the measure of
an interior angle after a 90° rotation around the point of symmetry?

answer:

C

Step-by-step explanation:

A rotation of the regular pentagon does not change the shape only it's position.

Thus the figures are congruent

The interior angle is therefore 108° → C

tube or goog would be a great resource to with that question

i belive those are the ones that are under 90 degreese.
