Step-by-step explanation:
We can do it in 2 methods.
<u>1st method:-</u> Let us count the number of intersections by drawing lines one by one.
1st line - 0 points=0
2nd line- new 1 point=1
3rd line - old 1 point + new 2 points with two old lines = 1+2
4th line - old (1+2) points+ new 3 points= 1+2+3
5th line - old (1+2+3) points + new 4 points=1+2+3+4
Like that from 35th line-1+2+3+4......34 =
<u>2nd method:-</u>
We have to choose 2 lines from 35 lines.
We can do it in ways = 595 points
