There are many possible answers: A sphere sliced by a plane. An ellipsoid with two equal radii, sliced by a plane parallel to them. A paraboloid sliced by a plane perpendicular to its axis. A cone.
A sphere, a cone, a section of a sphere or ellipsoid, a torus (doughnut) sliced by a plane perpendicular to its axis, a paraboloid. These are some examples.
They would be two right triangular pyramids.
I think you might be thinking of a trapezium. A triangle with the top point sliced off by a line parallel to the base.
There are many possibilities. The simplest one to visualise is a cube from which one vertex (corner) is sliced off by a plane that is not parallel to any of the faces.
The cross section of a figure is done by slicing part of the figure off a certain way. Inside the sliced area, there will be a 2-D figure. That 2-D figure is the cross section of the figure.

That conic section is a circle.When you slice a cone with a plane parallel to the base of the cone, the sliced section is a circle, and the portion of the original cone on the side of the vertex is again a cone.An isosceles cone would be the out come
coronal cuts....

When a cone is sliced parallel to the base then the shape produced is a circle. If the cone is sliced at an angle so that the cut goes completely through the cone then an ellipse is produced. If the cut is made perpendicular to the cone's base then the shape produced is a parabola.
A cone, or a parabolic section, or a section of a sphere like a hemisphere, or a torus (donut) sliced in half sideways.
In a polyhedron - a 3-dimensional object - a pair of parallel faces are two faces which lie in planes that are parallel to each other.Parallel faces need not be congruent. For example, consider a pyramid whose top is sliced off by a plane parallel to it base. The flat top and the base will be parallel faces but will not be congruent.
Plain sliced wood is cut parallel to the growth rings of the tree, resulting in a varied grain pattern. Quarter sawn wood is cut perpendicular to the growth rings, creating a straight grain pattern. Quarter sawn wood is more stable and less prone to warping, making it ideal for furniture and flooring. It also has a distinctive appearance with ray flecks. Plain sliced wood is more common and less expensive, but may be less stable and prone to warping.
A doughnut with a [radial] slice cut out of it. A sphere sliced by two parallel planes.
