The base of a pyramid is its bottom face, typically a polygon, which supports the entire structure. In the case of a square pyramid, for example, the base is a square, while in a triangular pyramid, it is a triangle. The shape and size of the base determine the pyramid's overall footprint and stability. Additionally, the base connects to the apex or top point of the pyramid through its triangular faces.

It has 5 faces. The "quadrilateral" part of the name describes the shape of the base of the pyramid. A pyramid has 1 face for every side of the base plus an extra one for the base. Thus a quadrilateral pyramid has a quadrilateral or 4 sided shape for the base and so has 4 + 1 = 5 faces.
A pyramid is the simplest shape but there are many other possibilities.
there are no square pyramids. they are not of the same
It isn't a cone at all, technically or otherwise, by definition. A cone has a circular base; a pyramid, a polygonal one. In fact I think it's strictly only a pyramid if it has a quadrilateral base - anything else being a "~hedron" where the "~" part describes the number of faces, such as the Tetrahedron (4 triangular faces).
a pyramid where each face is the shape of a triangle

All cross sections of a square pyramid that are parallel to the base are squares

No. A triangular pyramid describes a triangle whose base is a triangle (not just the sides which define it as a pyramid), whereas a rectangular pyramid is one whose base is a rectangle. A triangle and a rectangle are not the same (a triangle is not a rectangle, and a rectangle is not a triangle), so it would be incorrect to refer to a triangle-based pyramid as a rectangle pyramid.

A trapezium, except that when it goes through the apex, it becomes a triangle. If the pyramid is a right pyramid, then the cross sections will be isosceles.
A pyramid (3D)! Some examples: - triangular base pyramid - square base pyramid - rectangular base pyramid - cone
A pyramid has a square base.

The base of a square pyramid is a square. The pyramid has 4 faces making the base have four edges. SQUARE PYRAMID
