zero-dimensional examples: Endpoints of edges (vertices and corners) Zero-dimensional figures lie in two-dimensional planes. one-dimensional examples: Edges of figures (sides and arcs) One-dimensional figures lie in two-dimensional planes.
A point is 0-dimensional ... it has no length, breadth or height. A line is 1-demensional ... it has length, but no breadth or height. A square, circle, triangle etc is 2-dimensional ... each of them have length and breadth, but no height A cube, cylinder, sphere etc is 3-dimensional ... each of them have lenght, breadth and height.
a ray and a line
A point, in two dimensional space, is defined as an ordered pair.
The origin is located at the point whose coordinates are (0, 0) in 2-dimensional space or (0, 0, 0) in 3-dimensional space.
