A one dimensional object wouldn't really exist, if you know geometry, think a point or a line except the point or line isn't really visible, because it doesn't actually exist. 2D is more like a plane in geometry. Think a piece of paper, except it doesn't have any volume. Essentially, 1D just is, while 2D has length and width. Only when you get to 3D and have length, width and height do you actually have a object that exists.
An octagon is 2-dimensional, an octahedron is 3-dimensional.
1. The difference of two numbers are the numbers between them. The difference is found by subtracting the smaller number from the larger. In this case, 2 is subtracted from 3 (3-2) with a difference of 1. 3-2=1
It is the difference between the coordinates of two points in 2-dimensional space, measured in the horizontal direction.
The difference is that two-dimensional shapes have a length and a width while three-dimensional shapes have a length, width, and depth. While some examples of two-dimensional shapes are circle, rectangle, and triangle, example of three-dimensional figures are a sphere, cuboid, and a pyramid.
A solid angle is 3-dimensional, a planar angle is 2-d.
Area is a 2-dimensional measure. Perimeter is 1-dimensional and volume is 3-dimensional.

An octagon is 2-dimensional, an octahedron is 3-dimensional.
A square is a 2-dimensional figure, a cuboid is 3-dimensional.
A cuboid is a 3-dimensional object, an oblong is 2-dimensional.
In 2-dimensional space, it is the difference between their y-coordinates, in 3-dimensional space, it is the difference between their z-coordinates.
Parallel lines are two 1-dimensional objects that do not meet. Parallel planes are two 2-dimensional objects that do not meet.
Rectangular prism is 3rd dimensional, while a rec. is 2 dimensional.
The difference between multidimensional and dimensional scaling is in terms of relationship between physical characteristic and dimension. In the case of multidimensional scaling, each dimension can be connected to 2 or more physical characteristics, unlike dimensional scaling..
volume is a measurement of capacity, 3 dimensional. depth is a measurement of length, 2 dimensional.
A module is a 3-dimensional motif, and a pattern is a 2 dimensional decorative visual repetition.
A rectangle is a 2-dimensional (plane) object while a cuboid is 3-dimensional (solid).
