Show answer
The angle of incidence equals the angle of reflection.
Also accept: Angle of incidence = angle of reflection; i = r; The angle of the incident ray is equal to the angle of the reflected ray.
Common mistakes: the angles are always 90°; angle of incidence is greater than angle of reflection
