A piece of paper is a 2D object though it contains negligible thickness. Can anyone provide with more examples of 2D objects around us?
We live in a space which accommodates 3dimensional objects. Now a dot is 1 dimensional. If there is another dot inside the dot, which we can see, gives us a straight line or the concept of thickness. How do we realize a 4 dimensional object in the space we live in ?
There are 3 conditions in a dot. They are-
The dot can absorb
The dot cannot absorb but can accommodate another dot above it
The dot can accommodate another dot to the right or left
The dot can attract another dot towards it without real contact or float above the dot
Circles and concentric circles drawn with the above dots will give us a sphere
A two-dimensional object in space is an object that has only two dimensions: length and width. It has no depth or thickness.
Some examples of 2D objects around us include:
Thank you for your valuable input. I had doubt the computer screen example in mind which led me to ask this question.
The 2-dimensional shapes or objects in geometry are flat plane figures that have two dimensions – length and width. Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces. A square, circle, rectangle, and triangle are examples of two-dimensional objects.
