A protractor is commonly used to measure the incident angle of a light beam. Alternatively, an optical goniometer can provide accurate measurements of the incident angle with high precision.

What is the advantage of measuring the angle of reflection and angle incident on either side of the normal to the surface of the mirror?

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.
