That thing.
A two-dimensional figure, also called a plane or planar figure, is a set of line segments or sides and curve segments or arcs, all lying in a single plane. The sides and arcs are called the edges of the figure. The edges are one-dimensional, but they lie in the plane, which is two-dimensional. The triangle, the pentagon, the hexagon and the circle are just a few plane figures. Prisms and pyramids, for instance, are three-dimension figures.
It is a plane figure.
the figure defined by intersection of a cone and a plane.

a 2d shape A two dimensional figure can also be called a plane figure since it can be drawn in the two dimensional plane. Some examples include the triangle, the square, the circle, the pentagon, the hexagon, the parallelogram, the rhombus, etc.
A plane figure is 2-dimensional.

Polyhedron* * * * *A polyhedron is a 3 dimensional figure, not its face! The face of a 3-d figure is a plane figure. It may be a polygon, of a circle or some irregular shape. The main requirement is that it is a plane (2-d) figure: if not, it is not usually called a face.
A parabola is the figure formed by the intersection of a circular cone and a plane that lies parallel to the edge of the cone. (the cone does not have to be a right [90°] circular cone).
It is a plane figure.
