Question

Which of the following must be the true value of the statements below in that order.

Statement I: There are $'' n'',$ $(n \geq 3)$ straight lines, drawn in a plane, no two of which are parallel and no three pass through the same point, and the points of intersection of these lines are joined. Then the number of fresh lines, hence made is $\frac{n (n - 1) (n - 2) (n - 3)}{8}$

Statement II: Vertices of $n$ -sided regular polygon, joined to form a triangle then number of obtuse angled triangle, is $n .^{\frac{n}{2} - 1} C_{2}$ , if $n$ is even $(n > 4)$
