Not sure what is the difference between those two. I am reading a book and I can see few times they refer to le savais-tu? one thing that I am also puzzled is why do they use LE savais tu not just savais-tu. Anyone can explain thanks.

"Le savais-tu ?" signifie "Did you know this/that?".
"Savais-tu" signifie simplement "Did you know" et nécessite un complément afin d'en faire une phrase correcte.
Did you know it? and Do you know? are interpretations of le savais-tu ? and sais-tu ?
