Question

Does a point have no dimension?

Answer 1

yes a point is dimensionless

Answer 2

0D = Dot
1D = Line
2D = Plane
3D = Solid
4D = Space-time
5D = ...idk :P

Answer 3

Then how does it make a line?

Answer 4

What do you mean?

Answer 5

. <-- This is not a point, it's just a representation because a point has no height, no length, no thickness.

Answer 6

One dimension: A line, numbers, they have only a length;

Answer 7

2D: Shape, Length and width
3D: Solids, Length, width and thickness

Answer 8

What is the definition for a line?

Answer 9

4D Spacetime: 3 dimentional object travelling/moving through time and space.

Answer 10

Straight objects without depth and width.

Answer 11

Is it made of many points?

Answer 12

Um, you can see it that way :)

Answer 13

When a point has no dimension then how can a collection of points make a line?

Answer 14

A point has no length, depth, width, when you align then, you just created a length

Answer 15

take a point and send it in some direction through space
the path that it traces out is a line
the real number line is infinitely dense so now we are getting into some of the trickyness of infinity

Answer 16

here is the real number line (still a line, consisting of infinitely many points)
I can ask you to pick out the point 1

Answer 17

and there it is
I can also ask you to find numbers between numbers
so if I ask you to find 1.5 it should be on the line

Answer 18

My doubt is when a point has zero dimension, then how can it make a line that has one dimension?

Answer 19

similarly I can keep asking you to find points between the two we have already found
1.75 must be on the line
1.85
1.8
1.8243574687654365768....
etc. must all be on the line
therefore there are infintiely many points on a line
