Any. You can have a triangular pyramid (tetrahedron), a rectangular one, a pentagonal one, and so on. Similarly, you can have a triangular prism, a rectangular prism, and so on.
If you arrange them in the form of a tetrahedron - a triangular pyramid.
They are both 3d and they both form triangles on the sides to come up and make a point
An octahedron. It could be in the form of a heptagonal pyramid, a hexagonal prism, or a rectangular dipyramid (two rectangular pyramids stuck together along their bases).
Think in 3-dimensions and make a tetrahedron (a triangular pyramid).
It's a triangular prism - the two triangles form two ends, and the rectangles join the three sides.
One square and four triangles.
rectangles and triangles
The faces are always rectangles on prisms, so if it's a triangular prism the bases are triangles; if it's a rectangular prism, the bases are rectangles; if it's a hexagonal prism, the bases are hexagons. Any polygon can form the base of a prism. Some people also consider cylinders to be circular prisms. In which case any closed plane shape can form the base of a prism.
A square based pyramid has 4 triangular faces and 1 square face.
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.

A square pyramid has 5 faces. The four side faces are triangles, and the base is in the form of a square. This pyramid has 5 vertices and 8 edges.

Yes, Some can even be formed into a square and two triangles or a rectangle and one or two triangles. Just drop perpendicular(s) from the vertex (vertices) of the short side to the long side (that is to say, the two sides which are parallel). That will form one or two right triangles and a rectangle of some sort...could be a square--all squares are rectangles but not all rectangles are squares.
Yes, the word 'pyramid' is a noun; a word for a shape or structure with a polygon for its base and three or more triangles for its sides which meet to form the top; a word for a thing.The word 'pyramid' is also a verb: pyramid, pyramids, pyramiding, pyramided.
