The correct description of the pyramids of Giza is:
They are square pyramids. They have 5 faces. The 4 lateral faces are triangles, and the 5th face is a square base. Each pyramid has 5 vertices and 8 edges. The 4 lateral faces meet at a single point, or apex.
Square pyramids are defined by having a square base and triangular lateral faces that converge at an apex. The attributes you mentioned align well with the characteristics of square pyramids.
