Detailed explanation-1: -According to laws of reflection: The incident ray, the normal, and the reflected ray all lie on the same plane. The angle of incidence is always equal to the angle of reflection.
Detailed explanation-2: -The second law of reflection states that “the incident ray, the normal to the surface at the point of incidence and the reflected ray, all lie in the same plane”.
Detailed explanation-3: -According to the laws of reflection, the angle of incidence made by the incident ray with the normal must be equal to the angle of reflection made by the reflected ray with the normal i.e. i=r. So, the given statement is true.
Detailed explanation-4: -The first 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. The second law of reflection states that the angle of reflection is equal to the angle of incidence. Both angles are measured with respect to the normal to the mirror.
