Sphere
They would be two right triangular pyramids.
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.
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.

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.
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

A cone, or a parabolic section, or a section of a sphere like a hemisphere, or a torus (donut) sliced in half sideways.
A doughnut with a [radial] slice cut out of it. A sphere sliced by two parallel planes.

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.
Pin curls sliced from a shaping and formed without lifting the hair from the head
With refrigerator cookies the dough is formed into a roll and chilled in the refrigerator usually overnight. The dough is then sliced into rounds and baked.
