pyramid
A tetrahedron or triangular pyramid.
A triangular pyramid.
A vertex on a cube, for example, is where any three edges meet. On a pyramid (square type) it could be at the point on the top or the 4 bottom edges. :)
The only thing I can come up with would be a tetrahedron. You could make a pyramid with a square (open) base, I guess.
There cannot be a solid three sided figure. A solid 4 sided object is a tetrahedron.
