There are four lines in a plane no two of which are parallel. The maximum number of points in which they can intersect is :
4
5
6
7
By the given diagram of 4 non parallel lines
We can say that these lines would intersect at 6 points.
there are four lines in a plane , no two of which are parallel.the maximum number of points in which they can intersect is:
a}4
b}5
c}6
d}7
IS THERE ANY PROOF OR FORMULA FOR THESE KIND OF QUESTIONS?
