The Law of Reflection states that when light hits a surface, it is always reflected at the same angle it strikes the surface: the angle of incidence equals the angle of reflection. This is best demonstrated by throwing a ball at a smooth surface. The angle at which it hits will equal the angle at which it bounces back (45° going in equals 45° going out). The angle at which you throw the ball is called the angle of incidence, and the angle at which the ball bounces back is called the angle of reflection.
