prove that if l is a line that there is at least one point t

prove that if l is a line that there is at least one point that is not incident with l

Solution

Proof:

We very well know that a Triangle has three vertices, that is the three points are not collinear. If all the points of

this Universe lie on a single line I (that is be incident with it) then a triangle was never possible. However which

is not the case with the Universe, Triangles are certainly possible in it, therefore, there always be a point not lying

on I to make a Triangle with.
