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.
each side is equal to each other side. all 3 sides have the same length

The Earth.
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)
RAINBOW!
* 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.
Yes. Because of its locked orbit, the same side of the moon always faces the Earth.

Sides and faces are the same thing. A hexagonal prism has 8 faces and 12 vertices.
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.
The same side of the moon always faces the earth because of a phenomenon called tidal locking, where the moon's rotation period is the same as its orbit around the earth. This causes one side of the moon to always be facing towards the earth.
