When a square pyramid is sliced perpendicular to its base through a vertex, the cross section will be a triangle. This triangle will have one vertex at the apex of the pyramid and the other two vertices on the base, forming a triangular shape that includes one of the pyramid's edges and a segment of the base. The resulting triangle will be isosceles if the slice is made symmetrically.
When you cut a cylinder perpendicular to its base, the resulting cross section is a circle. This is because the cut slices through the circular base, maintaining the same radius throughout the height of the cylinder. The shape of the cross section remains consistent regardless of the height at which the cut is made, as long as it is perpendicular to the base.
A vertical cross section of a square pyramid is obtained by slicing through the pyramid along a plane that passes through its apex and is perpendicular to the base. This cross section typically takes the shape of a triangle, with the base of the triangle corresponding to one side of the pyramid's square base and the apex representing the peak of the pyramid. The height of the triangle reflects the height of the pyramid, while the base length can vary depending on where the cut is made. This representation helps visualize the pyramid's structure in a two-dimensional format.
It is a rectangle.
Yes, a square can be a cross-section of a pyramid, depending on how the cross-section is taken. If the cut is made parallel to the base of the pyramid and at a height where the sides are still straight and converge, the resulting section can be a square. However, this is only possible if the pyramid's base is also a square and the cut is made at the right height.
trapezoid
The cross section of a pyramid shrinks from the shape of the base down to a point as you move along its axis from the base to the apex. The cross section of a prism is constant along its axis.
It is a rectangle.

Circle: If the knife is perpendicular to the axis of the cone.Ellipse: If the knife is between (perpendicular to the axis of the cone) and (parallel to the side of the cone).Parabola: If the knife is between (parallel to the side of the cone) and (parallel to the axis of the cone).Hyperbola: If the knife is parallel to the axis of the cone.Triangle: If the knife is perpendicular to the base of the cone.Point: If the knife is parallel to the base the cone and through the apex

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.
It will be one of:a triangle if where the cross section cuts the base is through two adjacent sides;an irregular quadrilateral if where the cross section cuts the base is through two opposite sides but not parallel to a side of the base; ora trapezium if where the is the cross section cuts the base is parallel to a side of the base.
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.
It is a rectangle which is similar to the base.
