Case A )
Incident angle = 20 degree
Reflected angle = 19
Case B)
Incident angle = 42°
Reflected angle = 43°
Case C)
Incident angle = 70°
Reflected angle = 69°
From the above three sets of readings , we can conclude that the angle of incidence is almost equal to the angle of reflection.
Conclusion: angle of incidence= angle of reflection
