What are some examples of Sacred Tradition in the Catholic Church?

Currently I am doing a school project on why I believe **Sacred Tradition should be used along with Scripture**. What are some examples of Sacred Tradition throughout Church history? I would guess that the Rosary and the Marian Dogmas be considered Tradition but would traditions like the accounts of the Apostles' deaths and the account of Mary's birth be put in the category of Sacred Tradition? What are also some other examples of what the Catholic Church means by Sacred Tradition?
