The law of reflection states that the angle of incidence and the angle of reflection are always a) greater than 45 degrees each. b) less than 45 degrees each. c) equal in measure. d) different in measure

I believe the answer is C since the angle of reflection is equal to the angle of incidence. Both angles are measured with respect to the normal to the mirror.

 C) equal in measure.

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, theangle of reflection is equal to the angle of incidence . Both angles are measured with respect to the normal to the mirror.
