One side of a square would be untouched with only 3 triangle faces attached to it. To make an entire closed shape, it would need another part or some 3 dimensional bending would need to take place. A pyramid has 1 square face and 4 triangle faces. A pyramid could also have 4 triangle faces where one triangle substitutes the square face.
The only one i can think of is the square - based pyramid, with 4 triangular faces and 1 square
They can be any shape ! We have square and rectangular ones in my town (and there's at least a couple of triangular ones too !)
A triangular pyramid is a four sided 3D shape. All four sides are triangles. It resembles a 'traditional' pyramid, like the ones in Egypt. A triangular prism is a five sided 3D shape. It consists of two identical triangular sides connected by three identical rectangular sides. think of it as a cylinder with triangles on the ends and three sides instead of a smooth surface.
In math terms, a pyramid could have a square base, triangular base or another shape. The Egyptian pyramids (and Aztec ones) had a square base. So they had 8 edges (for on the base and 4 rising to the top) and 5 faces (4 facing up and the base).
Most of the common ones have already been named, so I will not be naming any. Prisms and pyramids are named according to the 2-dimensional shape of their base(s). For example, triangular prism or square based pyramid.

There are many possible shapes. The regular ones amongst them are the tetrahedron, the octahedron and the icosahedron.
There are an infinite number of possible answers. Tetrahedron. octahedron and icosahedron are the regular ones amongst them.

A pyramid is not a square, but it has a square base formed by four triangular sides. Pyramids like the ones at Giza in Egypt are five-sided geometric shapes (pentahedrons).
small square ones melt quickly
They are commonly round but there are other cymbals that are square and there are evev pentagon shaped ones
Because square ones would result in poor gas mileage.
A pyramid will have as many triangular faces as the number of sides its base has, plus one in the shape of its base. This means an octagon based pyramid has nine faces (eight triangular ones plus the octagon base).
