The laws of reflection states that angle of incidence is equal to the angle of reflection.
So, the angle of incidence = 45o ( which is half of 90o)
angle of reflection = 45o
So, the angle of incidence = 45o ( which is half of 90o)
angle of reflection = 45o

both of them would be 45as 180 - 90 = 9090/2 = 45
