Suppose $n$ straight lines are drawn on a plane. When these lines are removed, the plane falls apart into several connected components called regions. $A$ region $R$ is said to be convex if it has the following property: whenever two points are in $R$, then the entire line segment joining them is in $R$. Suppose no two of the n lines are parallel. Which of the following is true?
I think answer should be C..
No-convex regions are possible, isn't it?
Please correct me if i am wrong.
@Nitesh Tripathi I think region divided by n lines should be ---. n ( n + 1 ) / 2 + 1
