The law of reflection states that the angle of incidence equals the angle of reflection. Define the angle of incidence in terms of a line normal to the surface.

Respuesta :

It's the angle made by the incident ray when it's perpendicular to the surface. (Perpendicular lines are the lines that form a graph or like a 90-degree angle)

You've got the whole answer right there in your question. The angle of incidence is the angle between the line normal to the surface and the beam of light coming into the surface. (Normal means perpendicular.)
