We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles on the either side of the mirror.

For light incident upon a plane reflective surface, the angle ofincidenceis the same as angle of reflection.
They are the angles made by the incident ray and the reflected ray with the line perpendicular to the reflecting surface at the point of reflection.
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
The ray angle refers to the angle made by the light of incident and reflection on the reflecting surface.
When talking about reflection (normally with light), one works out the angle of incidence and the angle of reflection by drawing a line that is perpendicular (90 degrees) to the reflector and measuring the angle between this line and the ray of incidence/reflection. This line is called the normal line. It is easier to measure the angles of incidence and reflection on a flat surface, because it is easier to draw an accurate normal line.
The magnitude of the incident angle with the normal of the reflection surface and reflection angle with the normal of the surface are the same. The direction of the reflection is away form the surface and the incident is toward the surface.
REFLECTION: IF a light ray in incident on a surface if it bring back to same medium is called reflection REFRACTION: IF a light ray in incident on a surface and going to another medium is called reflection and there is a a law for refraction that is SNELL'S LAW
yes.
A incidence ray is the ray that strikes the reflecting surface (prior to reflection). A reflection ray is the ray is reflected from the reflecting surface (after being reflected).
For light incident upon a plane reflective surface, the angle ofincidenceis the same as angle of reflection.
They are the angles made by the incident ray and the reflected ray with the line perpendicular to the reflecting surface at the point of reflection.
According to law of reflection, the angle of incidence and angle of reflection are equal. If the incident surface is smooth specular reflection takes place where the light is reflected in a single direction.
Regular reflection means the incident rays parallel to each other fall on plane or smooth surface and reflects back equal to the angle of incidence is called regular reflection.
The reference line is the normal (perpendicular) to the surface.
The reference line is the normal (perpendicular) to the surface.
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
If the ray is incident at right angles to the reflection surface, angle of Incidence will be 90 degrees and so will be the angle of reflection. In such a case, the incident ray, the normal and the reflected ray coincide.
