Explanation:
The law of reflection states that when a ray of light is incident on a surface, then the angle of incidence (i) and the angle of reflection(r) are equal in measure.
Definitions:
Angle of incidence (i): angle made by the incident ray with the normal to the surface (mirror in the image) at the point of incidence.
Angle of reflection (i): angle made by the reflected ray with the normal to the surface (mirror in the image) at the point of incidence.

Answer:
Laws of Reflection:
a. The incident ray, the reflected ray, and the normal at the point of incidence are always in the same plane.
b. ∠i = ∠r. The incident angle is always equal to the reflection angel.
