How are sphinxes and pyramids similar?

The Great Sphinx and the pyramids of Giza form the Giza Necropolis, or the Giza pyramid complex, which is located not too far from the city center of Cairo. The Giza Necropolis consists of multiple pyramid complexes, each belonging to a different pharaoh from the fourth Dynasty (one of the ruling families). The Great Pyramid of Giza is the complex that belongs to the pharaoh Khufu, who ruled Egypt in the 26th century BCE as part of the fourth Dynasty. The second biggest pyramid belongs to Khufu's son Khafre. The other pyramids belong to Khafre's successor, Menkaure, and the queen Khentkaus I, who was possibly the daughter of Menkaure. 

The Sphinx has the most in common with the pyramid of Khafre because it is thought that Khafre's face is the one the Sphinx wears. The pyramids were made of large stone blocks, as was the Great Sphinx. One big difference, however, is that the pyramids were tombs whereas the Sphinx is a statue.
