The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface.
Or, in simpler terms, the angle of reflection is the same as the angle of incidence.

What is the angle of incidence if a reflected wave bounces off a mirror with an angle of reflection equal to 55º?
If a light ray is reflected from a flat mirror with a reflection angle of 55o then the angle of incidence was also 55o. When reflecting from a mirrored surface, the angle of incidence equals the angle of reflection.
What is a line of reflection?
A line of reflection is a reflected line, often off of a mirror. If a flashlight sends a beam of light at a mirror (the light is called the incident beam), the angle at which it hits the mirror will equall the angle at which the reflected beam of light (called the reflected beam), exits the mirror. This is called the Law of Reflection. This is why light is reflected from a mirror at the same angle at which light struck its surface.

What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.
How is the angle of reflection and angle of incidence related to each other?
If the reflection is off an even surface, they are equal.
How does the angle of how the wave hits the surface compare to the angle at which it reflects off the surface?
They are equal. Angle of incidence = Angle of reflection. This is the second law of reflection.
