The reference line is the normal (perpendicular) to the surface.
Angle of incidence can be anything. Angle of reflection is the same as angle of incidence.
Both are zero. Thereby it obeys the second law of reflection ie angle of incidence is equal to angle of reflection.
the angle of incidence is equal to the angle of reflection
The angle of reflection is 40 degrees. The angle of incidence is equal to the angle of reflection.

The reference line is the normal (perpendicular) to the surface.
The angle of incidence and reflection are reference to of a line normal or perpendicular to a surface. The incidence angle is the incoming ray angle relative to the normal line and the reflection is the outgoing angle relative to the normal line. Both angles are in the plane containing the normal line and the incidence ray.
The angle of incidence is ALWAYS equal to the angle of reflection! This is one of the laws of reflection.
The angle of incidence
Angle of incidence can be anything. Angle of reflection is the same as angle of incidence.
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.
0(zero) Angle of incidence = angle of reflection
The angle of reflection.
the angle of incidence is the initial ray angle and the angle of reflection is the reflected ray angle
light's angle of incidence is equal to the angle of its reflection. That the angle of incidence equals the angle of reflection
For a smooth surface, the angle of incidence is the same as the angle of reflection.
Both are zero. Thereby it obeys the second law of reflection ie angle of incidence is equal to angle of reflection.
