# intersection of lines and planes ?

if 6 lines are drawn in a plane , what is the maximum number of parts in which plane is divided by them ? If there are 'k' lines drawn in the plane then plane is divided into how many maximum parts ?

• What are your thoughts on this question so far? What is the answer for $k=2$? How about $k=3$? – G Tony Jacobs Mar 11 '14 at 6:29

=> $max_{sections}=(n+1)\cdot n/2 +1$
