Hypothesis
Alfred Wegener couldn't describe how the plate tectonics moved. So, scientists rejected his hypothesis.
plate tectonics
the similarities of this 3 theory is,,,, they are all theory....
Tectonics is the large scale processes effecting the crust. The large scale process that is accepted to be occurring is plate tectonics (crust separated into plates that move and interact). The theory of continental drift suggested that continents moved however it never proposed a mechanism, plate tectonics is that mechanism that explains what alfred wegener saw. So back to your question similarities between what i think you mean modern tectonics i.e. plate tectonics and continental drift is that they both suggest the crust is moving.
i dont know if its is true, but plate tectonics

A set of moving sections of lithosphere
Alfred Wegener proposed the hypothesis of continental drift in 1912, suggesting that the continents were once joined in a supercontinent he called Pangaea. His idea laid the groundwork for the development of the theory of plate tectonics.
Although it seemed to make a lot of sense, there was no known proof of HOW the continents would drift. It wasn't until years later that we gained knowledge of plate tectonics, which bolstered Wegener's hypothesis.

I think that continetal drift replaced his theory
