Correct. The further the tooth profile of an involute gear is from the base circle, the greater the involute pressure angle becomes. Since the pressure angle on the base circle is 0, and the pressure angle on the pitch circle is 20°, it can be inferred that the further the tooth profile of an involute gear is from the base circle, the greater the involute pressure angle will be
