While finding Vth at R2, i know the voltage at a, by finding the voltage at b, the VbVa will be the voltage through 1 ohm right?

The best way is to remove R2 and find the open circuit voltage across ab. You also need to define the polarity of Vth since it is arbitrary.While finding Vth at R2, i know the voltage at a, by finding the voltage at b, the VbVa will be the voltage through 1 ohm right?
