They don't, at least I have never seen one.
There are carvings with faces and bodies in the sandstone cliffs, and the carving of the Sphinx, with a human head, made from a huge block of sandstone that had been just sitting there in the sand.
These were ways that the ancient Egyptians tried to please their gods, so the gods would protect them, make their crops flourish, bless them with lots of children, and so forth.
Triangular pyramids have 4 faces(3 and a base) Traditional pyramids have 5 faces( 4 and a base)
Pyramids that do not have parallel faces are known as irregular or non-regular pyramids. Unlike regular pyramids, where the base is a regular polygon and the triangular faces are congruent, irregular pyramids can have bases of varying shapes and sizes, leading to non-parallel faces. An example of this is a pyramid with a base that is a scalene triangle, where the triangular faces can differ in size and shape.
No.
triangle... because pyramids are triangular therefore triangular pyramids have triangle faces

No, there are many different types of pyramids. To give a real-life comparison, the Egyptian pyramids are square pyramids, and have 5 faces. Triangular pyramids have 4 faces. (Count the base as one face) A pentagonal pyramid would have 6 faces. (Five on each side, plus the base) A hexagonal pyramid would have 7 faces, etc. (One for each side base + the base's face)
Pentagonal pyramids have six faces, ten edges, and six vertices. One of the faces is a pentagonal base, the rest are triangular.
15 faces on three
Because if their lateral faces were not triangular they would not be called pyramids!
no
Both pyramids and prisms are three dimensional. Both of them have polygon faces. Another thing common about pyramids and prisms is that they have a base and faces.
Do pyramids have perpendicular faces ?
