Imagine a pyramid, with a triangle shaped base, with three sides coming up each of which is a triangle. That is a tetrahedron (4 sides, all the same side, with each one the shape of a triangle). * * * * * Mostly correct, but the four faces need not all be the same.
Faces in mathematical terms are the surfaces of objects on each side. This includes things like the sides of a triangle or the outer surface of rectangles and squares.
If all faces are square then each side must be the same length and so it is a cube.

Yes ya you just see different portions and shadows of the moon. That's why there is the expression 'dark side of the moon' because it is always the same side that they are talking about (the side that always faces the sun)
The Earth.

* 27 edges: 9 on each end face and 9 other edges between the side faces. * 11 faces: two end faces and 9 side faces. * 18 vertices: 9 on each end face.

Sides and faces are the same thing. A hexagonal prism has 8 faces and 12 vertices.
Yes. Because of its locked orbit, the same side of the moon always faces the Earth.
Since a face of a 3d figure is the same as a side, you have two faces sharing a face! The result is lots of coincident faces!
A quadrilateral bipyramid is one possible answer. This is two pyramids with the same quadrilateral base - one on each side of the "base".
A face is each side of an object, usually excluding the base. In this case, 3 faces.
