    Answer:

    When a light ray impacts on a parallel mirror with an angle of incidence A compared with the normal to the surface of the mirror (this means a perpendicular line to the surface), the reflected light ray always is reflected with the same angle.

    This means that if the light ray incident normally, the reflected ray will be reflected normally.

    If the light ray insides from the bottom with an angle of 30°, the reflected ray will be reflected upwards with an angle of 30° (always measuring these angles from the normal of the surface of the mirror).
