If a planet is discovered through the Doppler technique and later found to have transits, we can determine its orbital period, physical size, and density. From the transit data, we can determine the size of the planet relative to its host star and its orbital period. From the Doppler data, we can determine the planet's mass (albeit not precisely). However, the rotation period of the planet cannot be determined from these observations alone.
