A plane figure is 2-dimensional.
Two three dimensional figures that have circular bases: Cone, and Cylinder.
2D figures have surface area, but no volume.
a two dimensional figure is flat. it only has length and width. three dimensional figures have length, width and height. A square is a 2 dimensional figure, but a cube is a 3 dimensional figure.
A cube is not a polygon. Polygons are 2-dimensional figures and a cube is 3-dimensional.
2 dimensional figures just have width and length, if you were to add the height dimension it would become 3 dimensional.
Talking about a "2-D polygon" is the same as talking about a "polygon." By definition a polygon is a 2-dimensional figure, so all polygons are 2-dimensional and anything that is not 2-dimensional cannot be a polygon. Of course, not all 2-dimensional figures are polygons.
No. Planes are 2-dimensional.
A plane figure is 2-dimensional.

All polygons are 2-dimensional figures bounded by straight lines. Since they are 2-d they are included in the set of all 2-d figures. But since they can only have straight sides, they cannot account for all 2-d figures.
Simple. The answer is zero. A 2-d shape has, by definition, no volume. Volume is a characteristic of 3-d shapes.
Plane figures are flat (2-dimensional) shapes.
