The base of a square pyramid is a square. The pyramid has 4 faces making the base have four edges. SQUARE PYRAMID
Neither a triangular nor a rectangular pyramid has a square base. A square pyramid has a square base.
The center of gravity of a square pyramidis a point in the pyramid where its weight is assumed to be concentrated.

The PYRAMIDS at Giza in Egypt. Hence the name 'pyramid'.
a square
It depends on the pyramid. If it is a square based pyramid, a horizontal plane will give a square cross section, a plane inclined by a rotation parallel to one of the base axes will give a rectangular cross section whereas a plane inclined by rotation along both basal axes will result in a parallelogram cross section. Not sure how you get a parallelogram from a pentagonal or hexagonal (etc) pyramid.
You cannot have a 2d pyramid - whether or not it is square based. The 2d cross section will depend on the plane of the cross section.
The following are some shapes having a square cross section: a cube, a cuboid, a square pyramid.
square pyramid
A trapezium.
It can be a square, a trapezium, a quadrilateral or a triangle - depending on the inclination of the plane which defines the cross section.
Depending on the inclination of the plane used for the cross-section, it could be a square, rectangle, trapezium, triangle.
A circle.
It is just called a square pyramid, but its not square. Its only square on the bottom, so they call it a square pyramid, or you can simply just call it a pyramid because a pyramid is a pyramid.
A square pyramid is a pyramid whose base is in the shape of a square.
