The critical angle is not the same thing as the angle of incidence.
There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection.
Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection.
It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.

When a light ray is reflected by a mirror is the angle of the light ray and the reflected ray different or the same?
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
How is the angle of incidence of light ray related to the angle of reflection?
For a smooth surface, the angle of incidence is the same as the angle of reflection.
Is the angle of reflection the same as the angle of incidence?
Yes.
What is the best angle of incidents?
The angle of incidence is the angle of which it item is reflected, this leads us on to the fact that the angle of incidence will always be the same as the angle of reflection.
What is the difference between angle of incidence and angel of reflection?
None. They are the same angle.
