Rotation property tells that if the image in the spatial domain is rotated by some amount then its spectrum which is obtained by DFT is also rotated by same amount. This is being showed with the example in .m file

f(m.n) as f(rcos θ,rsin𝝷)
Then DFT [f(rcos (θ+α),rsin (𝝷+𝞪)] = F [R cos (θ+α),R sin(𝝷+𝞪)]
