Question

What is direction of reflected ray

Answer 1

If incident ray is x degrees the it also become x degrees in opposite direction.
it travels in opposite direction

Answer 2

If Ri is parallel to the normal then Rr = N, that is, the reflected ray is in the opposite direction to the incident ray. If the incident ray is perpendicular to the normal then it is unaffected, Rr = Ri, this is a glancing ray.
