What are the properties of a 2D Shape?

Answer 1

Two-dimensional shapes are planar. Graphically speaking, they depend on only two coordinates--x and y, for instance--consisting of x units and y units, respectively. In the case of a coordinate system of more than two dimensions, then a 2-D shape would still depend on two coordinate directions. For example, in a spatial xyzcoordinate system (which is three-dimensional) a two-dimensional shape would be expressed with points such as (x,y,0), (x,0,z), or (0,y,z). Therefore, it would depend on either x and y, x and z, or y and z. 2-D shapes include the square, the triangle, the rhombus, etc. To understand it more easily, you can say that 2-D shapes do not have prominent or rugged parts. For example, speaking two-dimensionally you would have a square, whereas three-dimensionally you would have a cube, which is like an extended or prominent square.
