There are several cases when you would want to use the law of sines. When you have angle angle side, angle side angle, or angle side side you would use the law of sines.
The law of reflection states that the angle of incidence is equal to the angle of REFLECTION. Refraction is an entirely different phenomenon and has its own law.
Angle of incidence is equal to the angle of reflection

The Opposite Angle Theorem (OAT).
Law of Reflection!
Law of Reflection
Angle of incidence is equal to the angle of reflection
Use Snell's Law. Snell's Law is: Sin i divided by Sin r, where "i" is the angle of incidence and 'r" is the angle of refraction.
light's angle of incidence is equal to the angle of its reflection. That the angle of incidence equals the angle of reflection
The law of reflection states that when an object bounces off a flat surface, the angle it at which it hits the surface will be equal to the angle at which it bounces away.
I think you are asking about the law of reflection: The angle at which light hits an object, it reflects off at the same angle i.e. the angle of incidence equals the angle of reflection (The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection)
